The health of the population is largely dependent on What does human health depend on?

A healthy lifestyle is a complex concept that includes many components. This includes all spheres of human existence - from nutrition to emotional mood. A healthy lifestyle is a way of life aimed at completely changing previous habits regarding food, physical activity and rest.

In this article, we will try to consider in detail all the components of a healthy lifestyle, as well as to study the factors that interfere with human health and psycho-emotional balance.

The relevance of a healthy lifestyle is due to the increase and change in the nature of the loads on the human body due to the increase in the risks of technogenic and environmental nature and the complication of the social structure. In the current situation, concern for the health and well-being of the individual is associated with the survival and preservation of man as a species.

It is impossible to explain what a healthy lifestyle (HLS) is in a few words. According to the official definition, it is a way of life aimed at promoting health and preventing diseases. Supporters of a healthy lifestyle as a philosophical and sociological trend consider this concept as a global problem and constituent part public life. There are other aspects of the concept of healthy lifestyle - psychological and pedagogical, medical and biological, but there is no sharp distinction between them, since they all solve the same problem - strengthening the health of the individual.

Medical experts believe that 50% of health depends on lifestyle, the rest of the influence factors are distributed as follows: Environment- 20%, genetic base - 20%, health level - 10%.

A healthy lifestyle is a prerequisite and necessary condition for:

• Full development of the most different sides human life;
• Achievement by a person of active longevity;
• Active participation of a person of any age in social, labor, family activities.

Interest in this topic arose relatively recently (in the 70s of the XX century) and was associated with a change in lifestyle modern man, an increase in life expectancy, a global change in the human environment, an increase in the influence of environmental factors on human health.

Modern people began to lead a less mobile lifestyle, use large quantity food and have more free time. At the same time, the speed of life has increased significantly, which has increased the number of stress factors. Doctors note that the number of hereditary diseases is increasing every year. In this regard, the question of how to stay healthy (spiritually and physically) and at the same time live a long and active life becomes very relevant.

The benefits of daily routine

How to lead a healthy lifestyle? To begin with, you should reconsider the mode of the day. None of the charts healthy life cannot include going to bed after midnight and waking up at 2 p.m. on weekends. If you don’t have enough time for tasks during the day, you need to either reduce the number of tasks or complete them faster. This requires a systematic approach to time management.

A rational mode of work and rest involves a reasonable alternation of periods of physical and mental stress with periods of complete relaxation. In other words, sleep should be complete (7-8 hours for an adult) and rest on weekends should be just as complete.

The need for a balanced diet

Healthy eating is a very broad concept (voluminous scientific works have been written about this), but the basic principles of a rational approach to food are as follows:

Berries and cereals

• Restriction of animal fats;
• A significant restriction of animal protein foods (it is recommended to use mainly dietary meats - poultry, rabbit);
• Inclusion in the menu of an increased amount of plant foods;
• Exclusion from the daily diet of "fast" carbohydrates - sweets, muffins, soda, fast food, chips and other "junk" food;
• The transition to fractional nutrition (a small amount of food at a time);
• Exclusion of late dinner;
• Eating only fresh food;
• Optimal drinking regime;
• Optimization of the amount of food - it must correspond to energy costs;
• Exclusion of alcohol, restriction of coffee and strong tea.

Food should be exclusively natural and contain all the necessary macro- and microelements, vitamins. It is desirable that an individual diet was compiled by a dietitian.

Active lifestyle

Reasonable promotion of a healthy lifestyle necessarily includes items related to physical activity. Achievements of science and technology have greatly facilitated the life of a person, but at the same time significantly reduced his physical activity. People walk less and less: now you can order and receive goods and products without leaving your home.

However, to maintain the functional status of the body, movement is simply necessary. Beginners to practice a healthy lifestyle should be given physical exercise at least 30 minutes a day: motor activity is one of the main factors affecting human health. What kind of physical activity to engage in - everyone decides for himself, in accordance with his age, temperament and capabilities.

Physical education It can be:

• Classes in the gym;
• Sports walking or running;
• Classes in the pool;
• Bicycle rides;
• Home gymnastics;
• Yoga and qigong gymnastics.

Opportunities for the realization of motor potential are not limited - you can start with walking (it is better to walk in forest park areas), and then gradually increase the load. Particular attention should be paid to the health of the spine: the functional state (flexibility and mobility) of this section of the musculoskeletal system is the main indicator of the youth of the body. Remember that movement is life!

Rejection of bad habits

Smoking, alcohol, bad food habits (salty foods, chips, sweets, soda) are all factors that destroy health. A healthy and conscious life involves a categorical rejection of the above "pleasures" in favor of healthier options. Giving up bad habits is a key point for all adherents of a healthy lifestyle - this is where practice should begin.

The list of factors contributing to health promotion necessarily includes procedures to strengthen the body and harden. Improving the immune status is a complex event that requires a gradual and patient implementation. You can strengthen the body with the help of pharmaceutical preparations that increase defenses (Eleutherococcus, ginseng tincture), home herbal remedies, and also through hardening.

Hardening - not necessarily swimming in the hole and dousing cold water. To begin with, an ordinary contrast shower is suitable: at the same time, the temperature difference by initial stage may be minimal. Hardening of the body increases the immune status, strengthens the vascular system, stimulates the autonomic nervous system and raises the overall tone of the body.

Be sure to monitor the state of the psyche and nervous system. Excitement, stress, tension, irritability are the direct causes of early aging. In addition, a nervous state negatively affects physiological processes and contributes to pathological changes in the tissue and cellular structures of the body. And one more thing - if you are already angry and nervous, do it openly, do not accumulate negative emotions in yourself.

The list of preventive measures to strengthen and stabilize health necessarily includes control of body weight. Excess weight is always an additional risk of cardiac, vascular, endocrine and many other pathologies.

People over the age of 45 are advised to regularly undergo a full clinical examination: with age, the risk of diseases such as hypertension, diabetes, ischemic disease hearts. Identification of these and other ailments early stage is the foundation of successful therapy.

Health of each person and society as a whole is determined by a number of factors that positively or negatively affect the human body. Based on the conclusions of experts from the World Health Organization, several main groups of factors affecting human health have been identified. These health factors can influence both positively and negatively, depending on the points of application.

Physical activity as a factor in human health.

Physical activity is very important for the normal functioning of the body, since this factor greatly affects human health, ensuring normal operation physiological processes, organs and tissues can receive the necessary nutrients and are cleared of metabolic products. Physical activity does not include sedentary work and mechanical repetition of the same type of action. For the best effect, the load should be distributed over the maximum number of muscles. Another important factor is that professional sports are not very healthy, as they burn our bodies ahead of time. There must be a measure in everything.

Ecology as a factor of human health.

Contemporary ecological the state of the environment is one of the most influential factors on human health, of course not in a good way. One of the factors affecting the high life expectancy of villagers is clean air. The quantity and quality of natural energy that urban residents receive has a very large impact. It is not for nothing that we are very happy to go to nature outside the city, to those places where there are more trees and there are natural reservoirs. This should be done as often as possible.

Lifestyle as a factor in human health.

Lifestyle is also the most important factor human health. It would seem, what could be easier if we are already people? Everything is really simple, if only there was no “but”. A person has high mental abilities, but at the same time we love to imitate and mimic. For example, a person naturally considers himself the crown and master of nature, but why does a “perfect” creature want to be brave like a lion and strong like a bear, and so on. Why animals can remain themselves, but for some reason we need to be like someone else? No one talks about lions rescuing children from a fire or bears building bridges across a river. These examples may look silly, but such absurdities fill our life, turning it into nightmare from which you can’t wake up and it seems that there is no way out. We have forgotten who we really are and what our purpose is. After all, a person with his consciousness differs significantly from all living beings, while having very large “powers”, if he follows his goal, as the Guardian of the Earth. But, unfortunately, it turns out that one of the methods that make us come to our senses are illnesses that make us seek salvation, which in the end can lead a person to search for the meaning of existence. In Eastern countries there is a proverb "a disease is given to a person as a gift."

Rational nutrition as a factor of human health.

Rational proper nutrition cannot be ruled out, since it is the most important factor in human health, which acts “from within” us. The resources that are laid down in us by nature are exactly 2 times higher than the average life expectancy in a modern person. One of the main "burners" life force is malnutrition. Under proper nutrition different people imply different principles - separate nutrition, vegetarianism, omnivore, diets, calorie control, fasting and other types of nutrition methods. Each of the methods has its pros and cons, based on which you can choose a power scheme according to your requirements. The main point is just that. That you do not need to eat everything indiscriminately, you need to control this process to achieve certain goals.

Genetic inheritance as a factor in human health.

Genetics, as a health factor plays a huge role in our life. There are genetically congenital diseases that modern medicine is not yet able to completely cure. It is interesting to note that modern studies have found that some diseases (including psychosomatic disorders) are transmitted not through a change in the DNA molecule, but through labels that are attached to the genes. These marks appeared due to the experience gained during the lifetime of our ancestors (in this way, for example, a family curse is explained). In addition, it became known that under certain conditions, tags can be deactivated, changing the situation in the other direction. These conditions include: positive thinking, reading mantras or prayers, establishing harmonious interaction with others, as well as meditative methods, which is a miracle for our medicine and has been actively used by almost all traditions of the world since ancient times.

The state of health affects the well-being of a person, his physical, social and labor activity. The quality of life and the level of overall satisfaction depend on it. It is now believed that general health consists of several components: somatic, physical, mental and moral. It is formed under the influence of a number of external and internal factors that can have a beneficial or negative effect. Maintaining a high level of public health is an important state task, for which special federal programs are being developed in the Russian Federation.

The main factors affecting human health

All factors important for the formation and maintenance of human health can be divided into 4 groups. They were identified by WHO experts back in the 80s of the twentieth century, and modern researchers adhere to the same classification.

• socio-economic conditions and lifestyle of the individual;
• the state of the environment, including human interaction with various microorganisms;
• genetic (hereditary) factors - the presence of congenital anomalies, constitutional features and predisposition to certain diseases that arose during fetal development and during the life of a mutation;
• medical support - the availability and quality of medical care, the usefulness and regularity of preventive examinations and screening examinations.

The ratio of these factors depends on gender, age, place of residence and individual features person. Nevertheless, there are average statistical indicators of their influence on the formation of health. According to WHO data, lifestyle (50–55%) and the state of the environment (up to 25%) have the greatest impact. The share of heredity is about 15-20%, and medical support - up to 15%.

Lifestyle includes the degree of physical activity of a person and the presence of bad habits. This also includes the nature of the organization of work and leisure, adherence to the observance of the daily routine, the duration of night sleep, food culture.

Environmental factors are natural and anthroponotic (created by people) conditions in the place of permanent residence, recreation or work of a person. They can be of a physical, chemical, biological and socio-psychological nature. Their influence can be small in intensity and permanent, or short-term, but powerful.

Physical factors

Temperature, air humidity, vibration, radiation, electromagnetic and sound vibrations are the main physical factors affecting health. In recent decades, more and more importance has been attached to electromagnetic radiation, because a person experiences its effect almost constantly. There is a natural background that does not pose a health hazard. It is formed as a result of solar activity. But technological progress leads to the so-called electromagnetic pollution of the environment.

Waves of different lengths are emitted by all household and industrial electrical appliances, microwave (MW) ovens, mobile and radio telephones, and physiotherapy devices. Power lines, intra-house power networks, transformer stations, urban electric transport, cellular communication stations (transmitters), television towers also have a certain influence. Even the constant action of medium-intensity unidirectional electromagnetic radiation usually does not lead to significant changes in the human body. But the problem lies in the number of sources of such radiation surrounding a city dweller.

The massive cumulative influence of electric waves causes a change in the functioning of the cells of the nervous, endocrine, immune and reproductive systems. There is an opinion that the increase in the number of neurodegenerative, oncological and autoimmune diseases in society is also associated with the action of this physical factor.

The radiation factor is also important. All living beings on Earth are constantly exposed to natural background radiation. It is formed during the isolation of radioisotopes from various rocks and their further circulation in food chains. In addition to this, a modern person receives radiation exposure during regular preventive X-ray examinations and during X-ray therapy of certain diseases. But sometimes he is unaware of the constant action of radiation. This happens when eating foods with an increased amount of isotopes, living in buildings made of building materials with a high radiation background.

Radiation leads to a change in the genetic material of cells, disrupts the functioning of the bone marrow and the immune system, and negatively affects the ability of tissues to regenerate. The functioning of the endocrine glands and the epithelium of the digestive tract worsens, and a tendency to frequent diseases appears.

Chemical Factors

All compounds that enter the human body are chemical factors that affect health. They can be ingested through food, water, inhaled air or through the skin. The following can have a negative impact:

• synthetic food additives, flavor improvers, substitutes, preservatives, dyes;
• household and auto chemicals, washing powders, dishwashing detergents, air fresheners in any form;
• deodorants, cosmetics, shampoos and body hygiene products;
• medicines and dietary supplements;
• pesticides contained in foodstuffs, heavy metals, formaldehyde, traces of additives to accelerate the growth of livestock and poultry;
• glue, varnishes, paints and other materials for the repair of premises;
• volatile chemical compounds released from floor and wall coverings;
• preparations used in agriculture for pest and weed control, means for getting rid of mosquitoes, flies and other flying insects;
• tobacco smoke, which can get into the lungs even of a non-smoker;
• water and air polluted by industrial waste, urban smog;
• smoke from burning landfills and burning leaves from city trees (which accumulate heavy metals and other exhaust products).

Chemical factors that affect health are especially dangerous if they tend to accumulate in the body. As a result, a person develops chronic intoxication with damage to peripheral nerves, kidneys, liver and other organs. The work of the immune system is changing, which leads to an increased risk of developing bronchial asthma, autoimmune and allergic diseases.

Biological and socio-psychological factors

Most people place great importance on the role of microorganisms in maintaining a sufficient level of health. To destroy pathogenic (pathogenic) bacteria, some people use disinfectants for daily cleaning and washing dishes, thoroughly clean their hands, and even take antibacterial drugs for prophylactic purposes. But this approach is wrong.

A person is constantly in contact with a huge number of microorganisms, and not all of them pose a health hazard. They are found in soil, air, water, food. Some of them even live on the skin of a person, in his mouth, vagina and inside the intestines. In addition to pathogenic (pathogenic) bacteria, there are opportunistic and even beneficial microbes. For example, vaginal lactobacilli help maintain the necessary acid balance, and a number of bacteria in the large intestine supply the human body with B vitamins and contribute to a more complete digestion of food residues.

Constant interaction with a variety of microorganisms has a training effect on the immune system, maintaining the necessary intensity of the immune response. Uncontrolled intake of antibacterial agents, the use of unbalanced diets and lead to disruption of normal microflora (dysbacteriosis). This is fraught with the activation of opportunistic bacteria, the formation of systemic candidiasis, the development of intestinal disorders and inflammation of the vaginal wall in women. Dysbacteriosis also leads to a decrease in immunity and increases the risk of developing allergic dermatoses.

Social and psychological factors influencing health also play an important role. stressful situations initially lead to the mobilization of the body with the activation of the sympathetic nervous system and stimulation of the endocrine system. Subsequently, there is a depletion of adaptive capabilities, and unreacted emotions begin to transform into psychosomatic diseases. These include bronchial asthma, stomach and duodenal ulcers, dyskinesias of various organs, migraine, fibromyalgia. Immunity decreases, fatigue accumulates, the productivity of the brain decreases, existing chronic diseases become aggravated.

Maintaining health is not just about managing symptoms and fighting infection. Preventive check-ups are important proper nutrition, rational physical activity, competent organization of the workplace and recreation area. It is necessary to influence all factors influencing health. Unfortunately, one person cannot radically change the state of the environment. But he can improve the microclimate of his home, choose his foods carefully, keep his water clean, and reduce his daily use of pollutants.

The article was prepared by the doctor Obukhova Alina Sergeevna

Human health is the result of a complex interaction of environmental, biological and social factors. Scientists from all over the world have proven the following different effects on health:
— environment – ​​20%;
- heredity - 20%;
- lifestyle - 50%;
- the level of medical care - 10%;
According to Russian scientists, these figures look like this:
– human factor – 25% (Mental state – 15%, physical health – 10%);
- social factor - 40% (lifestyle: lifestyle, habits - 25%; material conditions of work and life - 15%);
— medical factor — 10%;
- environmental factor - 25% (endoecology - 15%, exoecology - 10%).

Man and his health

A person with full health can be identified by the following main criteria: the absence of bruises under the eyes, the absence of yellow teeth, as well as the bright red color of the tongue and the absence of white plaque on it. If you found at least one sign out of three, then this means that your health is undermined by some kind of disease. It is easy to correct it and strengthen the protective functions of the body, the main thing is to know what exactly is the reason for the deviation in health, what undermines it. It is necessary to find out the disease and what exactly contributes to its development in the body. Whatever disease a person suffers from, it can be cured or the influence of the disease can be weakened as much as possible, the main thing is to find the cause of the symptoms or frequent ailments, deterioration of health in time. For any signs feeling unwell, illness, or its initial stage, you should immediately seek help from your doctor. Which, after examination, should identify the cause of the symptoms, make a diagnosis and prescribe treatment or refer to a specialist in the required profile.

How to prevent disease.

In order not to get sick, you must first improve your health. There are many ways to boost immunity from folk remedies to medical drugs. Someone gives more preference to grandmother's recipes and advice that have been tested for decades, others even test themselves and their bodies on various dietary supplements and food supplements, but all of them in one way or another turned to professional medicine, the progress of which is observed on a significant scale. If you have already had a particular disease and the appearance of which you want to prevent, there may be a possibility of another occurrence of another disease - you should consult with your doctor. He, in turn, can recommend you:
- get the appropriate vaccination;
- the necessary drugs to increase immunity;
- write down the most suitable vitamins for you or food supplements containing them;
- will acquaint you with his special prescriptions (they can be a diet, daily routine, living conditions, environment, and more).
In order to be not only healthy, but also energetic, you need to lead a healthy lifestyle. A person, in order to support his immune system, should exclude from eating alcohol, semi-finished products, daily consumption of confectionery and flour products, canned foods, smoked products. An integral part of the diet should be foods rich in vitamins: fruits, vegetables, herbs, cereals, berries safe for the human body, fresh meat (fish, beef, pork, chicken), as well as fresh dairy products, especially kefir, bifidok, cottage cheese . Go in for sports, fitness, yoga, do exercises, if conditions allow, warm up at school, during work, after it and at home. Create an enabling environment for both your study and labor activity because they directly affect your health.

What does human health depend on?

Favorable conditions for study and work

These may include the following factors:
— illumination of a working or educational place;
- room temperature;
- humidity;
— air pollution;
— industrial noise and vibrations;
- the location of the place;
- harm at work;
- what is connected with the manufacture of products in production (if it is a plant or factory);
— the degree of labor safety.
Working conditions must be drawn up in accordance with the norms of the labor code.

It is important not to forget how bacteria enter the body. Most often this happens through the respiratory system of the human body: microbes and bacteria, a particular virus or disease enter through the nose, mouth, dirty hands, wounds. Always wash your hands thoroughly before eating, take precautions to prevent airborne transmission of the virus, eat freshly prepared homemade food.

Lead a healthy lifestyle, take care of yourself and your loved ones.

Healthy lifestyle- the concept is complex, consisting of many components. It includes all spheres of human existence - from nutrition to emotional mood.

A healthy lifestyle is a way that involves a complete rejection of old habits regarding rest, physical activity and nutrition.

To better understand what a healthy lifestyle is, you need to consider all the components and understand what interferes with a person’s psycho-emotional balance and his health.

Why in last years more and more talk about a healthy lifestyle? Well, first of all, this is due to the fact that the loads acting on the human body have increased and changed, which is associated with an increased risk of an environmental and man-made nature, as well as with a more complicated social structure. In such conditions, in order to survive, each individual must take care of their well-being. On a global scale, this means the preservation of man as a species.

In a nutshell, it is difficult to explain what healthy lifestyle means. According to the official definition, its essence is to prevent diseases and improve health. This concept is considered by supporters of a healthy lifestyle as a philosophical and sociological direction, as

integral part of social life and global problem. But there are other aspects of this concept: medical-biological and psychological-pedagogical. But, since they are all aimed at solving one problem - strengthening the health of the individual, there is no sharp distinction between them.

Doctors tend to believe that 50% of a person’s health depends on lifestyle, and other factors affect it in the following percentage: 20% is the genetic base, 20% is the environment, 10% is the level of healthcare.

A healthy lifestyle is a prerequisite and necessary condition for:

• full development of all aspects of human life;
• achievement of active longevity;
• participation in labor, social and family activities of a person of any age.

For the first time this topic was raised in the 70s of the last century. This was due to the increased influence of environmental factors on health, global changes in the human environment, changes in his lifestyle, and an increase in its duration.

Modern man began to eat more food, while he leads a less mobile lifestyle. At the same time, the speed of life increased, which led to an increase in the number of stress factors. This affects the growth in the number of hereditary diseases, the number of which is increasing year by year. In such a situation, it is already impossible not to think about how to stay healthy physically and spiritually, leading an active lifestyle.

To stay healthy, you need to reconsider your daily routine. Late going to bed (after midnight) and early awakening (at 4 am) do not contribute to this at all. If you don’t have enough time to complete all the tasks in a day, then you need to either reduce their number or learn how to do it faster, i.e. You need to learn how to manage your time properly.

The rational mode is, first of all, the alternation of work and rest, i.e. periods of mental and physical stress and periods of complete relaxation. In other words, for a good sleep, an adult should allocate 7-8 hours a day, including on weekends.

The need for a balanced diet

Equally important is a balanced diet. This concept is quite broad and a lot of voluminous works are devoted to it.

However, in this variety, the basic principles can be traced:

• you need to limit the intake of animal fats;
• limit the intake of foods rich in protein (primarily fatty meats);
• include an increased amount of vegetable products in the menu;
• completely eliminate the consumption of "fast" carbohydrates - muffins, sweets, fast food, carbonated drinks, crackers and chips;
• switch to fractional nutrition, i.e. multiple (up to 6 times a day) meals, but significantly reducing its amount per meal;
• forget about a late dinner;
• include only fresh foods in the diet;
• adhere to the optimal drinking regimen;
• exclude alcohol, limit strong tea and coffee;
• optimize the amount of food, adhering to the rule that the number of calories received should not exceed energy expenditure.

Consumed food products should be exclusively natural, containing the necessary vitamins, micro- and macroelements. It is very good if the preparation of the diet takes place under the guidance of a dietitian.

HLS is also physical activity. The life of modern man has become easier and more comfortable than it was for his ancestor. For this, thanks must be said to the achievements of science and technology. At the same time, it was because of this that the person began to move less. Now you do not need to go to the store, because the products can be ordered with home delivery, as well as the purchase of things, furniture, electronic equipment.

But in order to maintain the functional status of a person, he needs to move. Beginners to practice a healthy lifestyle should spend at least 30 minutes a day on physical exercises. Which sport to choose, everyone must decide for themselves. It is chosen depending on temperament, capabilities, age and, possibly, existing skills.

Someone will prefer classes in the training room, walking or running, and someone will like to go cycling, go to the pool or do yoga, gymnastics, qigong.

There are many opportunities to realize the motor potential. Even walking will be very useful at the initial stage. It is clear that over time, the load must be increased. A special place is occupied by exercises for the spine. This part of the musculoskeletal system is responsible for how young your body looks. Life is motion! This means that the spine must remain mobile and flexible.

Rejection of bad habits

Everyone has heard many times that the body is destroyed: food addictions (chips, crackers, soda, salty foods), bad habits(alcohol, smoking). All this should be abandoned in favor of healthier options. The practice of ZOH should begin with the abandonment of bad habits.

Prevention of diseases and strengthening the body

Procedures for hardening and strengthening the body are necessarily included in the list of factors that contribute to health promotion. There are several methods that will help strengthen the immune system: using pharmaceutical preparations (ginseng tincture, eleutherococcus, etc.) and hardening.

It is not necessary to immediately climb into the hole. At first, a contrast shower is suitable. Moreover, the temperature difference should be small at first, but gradually it should be increased. This will strengthen the vascular system, immunity, raise the overall tone of the body and will be a good stimulant for the autonomic nervous system.

Behind nervous system and the state of the psyche must be monitored, since it is stress, irritability and nervousness that are the direct causes of rapid aging. Nervousness negatively affects the cells and tissues of the body, leads to their pathological changes. Another tip: if you are nervous and angry, then at least do not accumulate negativity in yourself, show emotions openly.

It is necessary to say about one more factor that plays an important role in the prevention of health - body weight. It needs to be controlled, because excess weight is an additional risk of developing vascular, cardiac, endocrine, oncological and other diseases.

With age, this risk increases, therefore, after 45 years, everyone needs to undergo a full examination at least once a year in order to prevent or detect diseases such as coronary heart disease, diabetes, hypertension, etc. in the early stages. Detecting diseases at an early stage is the key successful therapy.
