Five interesting facts about the female body. The Importance of Proper Nutrition

What do we know about human body? Basically what you remember from school curriculum. However, our body is an amazing phenomenon and still holds many mysteries for scientists. Our body is a rather fragile system, which, nevertheless, can survive in different conditions.

We perceive our body as an integral part of ourselves, but we know very little about it. For example, men and women differ not only in outward signs, character and behaviour. Today we bring you a selection of amazing facts about female body which you may not have even thought about.

25 most unusual facts O female body:

1. A woman's heart naturally beats faster than a man's.
2. Women blink twice as often as men.
3. A woman's body burns fat much more slowly than a man's - about 50 kcal per day.
4. Women have stronger immunity.
5. The diameter of a woman's hair is 2 times smaller than that of a man's.
6. The corpus callosum in the brain of a woman is thicker than that of a man. It contains 30% more compounds. This is what allows women to better cope with several tasks at the same time.
7. A woman's tongue has more taste buds.
8. There are more pain receptors in the body of women, however, thanks to estrogen, which blocks inflammatory processes women in general have a lower pain threshold.
9. Women can better distinguish shades and colors, since color discrimination is directly related to the X chromosome.
10. A woman's skin is 10 times more sensitive than a man's.
11. The muscles and ligaments of the female body contain more elastin, so women are more flexible.
12. Women better than men can distinguish high frequency sounds.
13. The activity of the female brain during sleep is reduced by only 10%, so women's sleep is more sensitive.
14. Women can better distinguish different shades of sweet taste.
15. Women are by nature less oriented in space, because of this, problems may arise while driving. For example, parallel parking is obtained by 82% of men, while about 70% of them can do it on the first try. For women, the results are quite different. Only 22% of women succeed in such parking, and only 1/3 of them can do it on the first try.
16. The speech of women is controlled by 2 think tanks. That is why women can easily pronounce up to 8,000 words a day, use about 3,000 sounds and 10,000 non-verbal signals. The same figures for men are about 2 times lower.
17. Women naturally have a better sense of smell.
18. Women have better developed peripheral (lateral) vision, while men have better central vision.
19. The female neck is more mobile than the male. When a woman is called, she usually simply turns her head, and a man in the same situation turns his whole body.
20. Baldness is an X-linked recessive trait that a man inherits from his mother.
21. Due to the presence of two X chromosomes, the female body is less prone to the manifestation of complications and chronic diseases.
22. Women are emotional by nature, crying on average about 30–60 times a year, while men cry 6–17 times.
23. About 30% of women may feel the desire to eat inedible things during pregnancy.
24. Women are more prone to anxiety and a sense of danger due to high level hormones progesterone, cortisol and estradiol. That is why women intuitively better anticipate the threat and danger.
25. Women bond more strongly with men due to higher levels of oxytocin. Women also have more developed areas of the brain that are responsible for feelings of affection.

According to materials:

Almost everyone knows about monthly women's "problems". What is called, from small to large. Acquaintance with the female body and its features begins from the school bench, and these are the paragraphs that are read long before the biology teacher asks them. Usually this happens already when the student is given a stack of textbooks for the next year.

Despite the increased interest from this young age of both boys and girls to the issues of femininity, conception, pregnancy and childbirth, when the time comes, few parents are able to understand and understand (what is called “on the fingers”) to tell their growing child about the menstrual cycle and everything else connected with it.

Often in such situations, the child is “enclosed” with certain literature, which describes in detail the changes in the body of a girl in puberty. This is quite justified, the main thing here is to choose competent and intelligible material. Sometimes this is done because of the "shyness" of the parents or their unwillingness to talk with their offspring on "this" topic. But, unfortunately, in some cases this is due to a misunderstanding of such issues by the parents themselves, including mothers who are faced with cyclical transformations of their body on a monthly basis.

Let's try to at least partially understand what happens to a woman's body at a certain stage of her life.

To begin with, it would not hurt to drown out what the female cycle is. Everyone knows that the menstrual cycle is recurring from month to month. various changes uterus, and vagina. But not only these organs! The mammary glands are also subject to cyclical changes, hair follicles, skin, bones, adipose tissue and the whole organism as a whole. Outward manifestation these complex processes is menstruation.

Normally, the first menstruation, or menarche, appears at 11–16 years of age. Since that time, it is generally accepted that a woman's body is capable of conceiving and carrying a pregnancy. This ability persists on average up to 45-50 years, and sometimes much longer. Then there is a gradual "fading" menstrual function, which is most often expressed in a decrease in menstruation, a decrease in their duration and the volume of blood released during menstruation, up to their complete cessation. This period is called om.

The first day of menstruation is considered to be the first day female cycle, its beginning, and the last day of the cycle is the day before next menstruation, with the beginning of which a new cycle begins. And do not be afraid if the cycle is shorter or longer than others. It's very individual. Normal cycle it is considered when at least 21, but not more than 35 days pass from the beginning of one menstruation to the beginning of another. In 60% of cases, there is a 28-day menstrual cycle.

Another important characteristic of it is regularity, the absence of which is permissible only for one to one and a half years after menarche. The duration of the spotting(monthly) normally ranges from 2 to 7 days. They should not be very scarce or excessively abundant, gynecologists believe that the volume of blood that a woman loses these days normally corresponds to 20-80 ml.

It should be remembered that when normal flow menstrual cycle a woman may feel some discomfort in the lower abdomen, in lumbar region, but should not experience severe pain.

Usually, two phases of the menstrual cycle are distinguished, conditionally separated from each other by the "birth" of the egg - ovulation. The appearance of this special cell of the female body comes from a rounded formation that has a complex multicellular structure - the follicle.

Approximately 500 million follicles have already been laid in the body of an unborn girl, of which only 10% of women receive at least some further development. The fate of the rest is to be on the “bench”, in reserve. Already by the time of menarche, the number of follicles is halved from those originally laid down by nature. And only about 400 follicles for the entire period, while a woman has menstruation, reach their full development, ensuring the woman's ability to conceive.

The first phase of the menstrual cycle is called folliculin. It occupies the entire first half of the cycle, that is, from its first day to the rupture of the follicle with the release of the egg. That is, with a 28-day cycle, this phase usually lasts from the first to the fourteenth day. With the onset of the follicular phase, the special cells of the woman's brain during a series of complex biochemical processes they secrete a hormone into the blood. This is a follicle-stimulating hormone that acts on the ovaries, causing them to grow several follicles at once.

At first, the growth rate of follicles is approximately the same, but gradually one of them begins to outstrip the others, to dominate. The rest, as if having lost "hope to be the first", slow down their growth and gradually return to their original "rudimentary" state. The “leader” follicle, on the contrary, accumulates in itself more and more “vital juices”,

grows and grows stronger, sometimes reaching up to 2-2.5 cm in diameter. The role of this is very important education ovary - release into the blood of another hormone - estrogen.

The effect of estrogens is experienced by the female body even when it is in the "stomach of the mother." Mother's hormones, penetrating into the developing daughter organism, determine proper development female genital organs. In other words, estrogens play a very important role during all periods of a woman's life. It is to them that a woman owes her beautiful, smooth skin. They prevent the formation and excessive development of hair on the skin. Estrogen (like progesterone) strengthens bone tissue, normalizes the work of the cardiovascular and other systems.

Here are some of the functions of estrogen:

• the development of secondary sexual characteristics of a woman during puberty (development of the mammary glands; special type hair growth and distribution of adipose tissue, characteristic of the female body);
• improve blood supply to the uterus;
• promote the growth of the internal uterine lining (endometrium) in the first phase of the menstrual cycle;
• increase sexual attraction women in the middle of the cycle, which corresponds to the moment the egg leaves the follicle, and therefore contribute to the implementation of the process of conceiving a child laid down by nature;
• facilitate the penetration of spermatozoa into the uterine cavity during the period of ovulation through the mucus located inside the cervical canal, as they reduce the viscosity of this mucus itself.

When the dose of estrogen in the blood reaches a certain level, the woman's brain begins to produce another very important factor- luteinizing hormone. This leads to the rupture of the follicle, that is, ovulation. This usually happens in the middle of the menstrual cycle,

around day 14.

Now the egg released from the follicle should get inside the uterus, which is possible only along the thin “petal” of the fallopian tube (fimbria), which, under the influence of the same estrogen, “lays down” on the surface of the ovary exactly where the follicle burst.

Each healthy woman reproductive age periodically occur short bleeding from the genital tract, which is called menstruation.
The periodic onset of menstruation is associated with complex and varied cyclical changes that occur in a woman's body. Knowledge of the female body, providing complete and varied information about contraceptive methods are very important for the prevention of early pregnancy, for the correct sexual education of girls.
The whole complex of changes in the female body that occur cyclically and are externally manifested in periodically occurring menstruation is called menstrual cycle.
In practice, the beginning of the menstrual cycle is considered to be the first day of the next menstruation. And the duration of the menstrual cycle is the period from the first day of one menstruation to the first day of the next. The normal length of the menstrual cycle ranges from 21 to 35 days, with most women having 28 days. The duration of each menstrual bleeding is approximately 3-4 days, although it may vary depending on many factors.

The regulation of menstrual function is carried out using 5 links:

* cerebral cortex;

* Subcortical centers located mainly in the hypothalamus;

* An appendage of the brain - the pituitary gland;

* Gonads - ovaries;

* Peripheral organs - fallopian tubes, uterus, vagina.

Cyclic functional changes that occur in a woman's body affect not only her sexual apparatus, but are also expressed in changes in the activity of the central nervous system,of cardio-vascular system, metabolic processes, thermoregulation, etc.

ovaries are the female gonads that perform two important features body:

* They undergo periodic maturation of follicles and ovulation, resulting in the release of female sex cell - ovum;

* They produce female sex hormones: estrogen and progesterone, and
also in a small amount of male sex hormones - androgens.

Both of these functions are closely intertwined with each other and an absolutely necessary component for the body to carry out the menstrual reproductive function.

Periodically, or rather, closer to the middle of the menstrual cycle, a follicle matures in the ovary (a vesicle inside which the egg is located); its dimensions are 2 cm in diameter. Under the influence of increased pressure inside the follicle, as well as under the influence of hormones, the wall of the follicle in the area of ​​the free edge is torn, and the egg is released into fallopian tubes and then into the uterus. There is a so-called ovulation. When the wall of the follicle is ruptured, a small hemorrhage is formed in the cavity, and the epithelial cells of the follicle begin to multiply, and in
there is an accumulation of fat cells (lipids), which leads to the formation of the so-called corpus luteum.
If by the time of ovulation (exit from the follicle of a mature egg) fertilization has not occurred, then the corpus luteum undergoes reverse development and after a few days, the inner lining of the uterus is rejected (menstruation begins). Then the menstrual cycle is repeated anew. If fertilization has occurred, then the corpus luteum continues to develop up to 16 weeks of pregnancy, while producing the hormones necessary to preserve it.

Follicle and corpus luteum are glands internal secretion that produce sex hormones. The follicle is able to produce a number of sex hormones: estrogens, gestagens and androgens. During menstruation, the inner lining of the uterus, the endometrium, is shed and ruptures.
blood vessels that permeate it. After the end of menstruation within a few days, the endometrium is restored by reproduction epithelial cells. This process occurs under the influence of estrogens produced by the follicle.

In the following days, an increase in the glands of the endometrium is observed, mucus is secreted, the inner layer of the uterus becomes loose and full-blooded. This whole process occurs under the influence of progesterone, the hormone of the corpus luteum of the ovary. In the cessation of production corpus luteum progesterone, endometrial rejection occurs again, blood vessels open and begins
menstruation. In the ovary, the follicle, which produces estrogens, matures again, and the whole uterine cycle repeats.
During the menstrual cycle, there are changes in the activity of all endocrine glands, the cardiovascular system, changes in metabolism, etc. For example, before and during menstruation, some women notice a change in mood, irritability, a tendency to tan, enlargement of the mammary glands and etc.

Normal menstrual function is carried out as a result of the activity of many links of neuroendocrine regulation. If one of the links in this chain is violated, menstrual cycle disorders of various nature may occur.

The reasons for such violations can be:

* Stress, mental and nervous diseases;
* Eating disorders (obesity, beriberi);

* Occupational diseases caused by exposure to certain chemical substances, radiation and much more.

Menstrual dysfunction may occur in different periods life of a woman and are clinically manifested in different ways.
Amenorrhea- absence of menstruation for 6 months or more.

Algodysmenorrhea are menstrual disorders clinical signs which are sharp pain in the lower abdomen during menstruation, as well as the appearance before menstruation of such symptoms: general malaise, irritability, pain in the mammary glands, a feeling of heaviness in the lower abdomen.

For all violations, you must consult a doctor. They can be signs of a serious illness.

People tend to experience a wide variety of feelings: love and hostility, joy, happiness and sadness. They arise in response to external factors. The body produces special substances - hormones that regulate the flow of blood. biochemical reactions in its various departments and the transmission of impulses to the centers of the brain. Each person has his own set of these substances that affect his health, mood and temperament. An important role is played by the so-called hormones of joy, which are responsible for positive emotions that make people cheerful and energetic.

What are hormones and neurotransmitters

Hormones and neurotransmitters are called biologically active substances stimulating work various bodies when exposed to cell receptors. Hormones are produced in endocrine glands and by blood vessels spread throughout the body. They induce the cells of various tissues to produce chemicals necessary for the flow of biochemical processes and the functioning of organs.

Neurotransmitters are produced in nerve cells. These substances transmit impulses directly to the brain, from where a response signal comes from, forcing a person to make certain movements, think, digest food, and so on. There are biologically active substances mixed type, which manifest themselves in the body both as hormones and as neurotransmitters (for example, dopamine, norepinephrine).

Hormonal background and its features

A certain set of hormones is formed in the body, and their ratio is normal so that all organs work correctly, and the person feels healthy. This does not mean that the combination of hormones should always be constant. The background within certain limits changes throughout life as they grow older, changes in physical and mental stress. The ratio of such substances depends on the sex of the person, his physiological state, age.

In men, the ratio is more stable. In women, due to the peculiarities of functioning reproductive system and monthly fluctuations in the level of sex hormones, it is constantly changing. It is thanks to this that the representatives of the weaker sex are more excitable, capricious, they are characterized by frequent drops moods. Hormonal imbalance can lead to neoplastic diseases, sexual disorders, developmental pathologies, and depression.

Organs that produce happiness hormones

The main center that regulates the production of hormones of joy and happiness in the body is the hypothalamus. According to its signal, hormones are produced in the pituitary, thyroid, parathyroid, pancreas, adrenal glands, as well as in the ovary in women and testicles in men.

Cells that produce hormonal substances are also found in organs that are not related to endocrine system such as the liver, kidneys, placenta, gastrointestinal tract and others. So, for example, with a lack of estrogen in the body, adipose tissue begins to produce them. In pregnant women, the placenta becomes the organ that produces hormones.

What substances are considered hormones of joy and pleasure

There is a relationship between the production of various hormones and a person's mood. His feelings and actions largely depend on how he slept, what he ate, with whom he communicated, what he learned new things. The impressions received by him are reflected in the brain. And here, signals are immediately produced that regulate the production of the corresponding hormones. Arises reciprocal feeling pleasure or frustration, peace or angry indignation.

The main hormones of joy, satisfaction, pleasure and happiness are called:

• endorphin;
• dopamine;
• serotonin;
• oxytocin.

Directly affect the behavior and mood of a person and substances such as adrenaline and norepinephrine.

endorphin

Weakens the impact of negative factors.

This substance is produced in the pituitary gland at the moment when a person enters stressful situation. Sharp increase concentration of endorphin in the blood leads to the fact that weaken pain, easier to carry mental trauma, there are forces to overcome stress. Endorphin acts like opiates, bringing a person into a state of peace and happiness, mobilizing him, giving him a chance to think about the situation and make an adequate decision.

Improving the state of the nervous system has a positive effect on the work of the heart and blood vessels, helps to strengthen the immune system. The level of endorphin in the blood increases sharply in women on recent weeks pregnancy. In this way, the body prepares to overcome the fear of childbirth and relieve pain. Endorphin "jumps" in athletes during the competition. It is noticed that it is the surge of this hormone in soldiers that makes them bold and decisive during the battle.

Its similarity to opiates, however, also plays a negative role, since this substance, like drugs, is addictive. If a person tries to artificially increase its content in the blood, he takes special means, then the production of its own endorphin decreases. Everything is required to get pleasure and joyful emotions large dose drug. In addition, it is easy to overdose.

With a lack of the hormone of happiness, a person is apathetic, suffers from depression, and experiences anxiety. An overdose makes him aggressive, inadequate, makes him take unnecessary risks.

Dopamine

Hormone of satisfaction and joy.

It is produced in the neurons of the brain and in the cells of the adrenal glands. An increase in his concentration occurs even at the moment of planning something pleasant: a welcome meeting, an interesting trip, or making a very necessary purchase. Dopamine levels peak when the result is achieved. It inspires him, makes him set new goals and strive to achieve them.

Due to the production of dopamine, people form conditioned reflexes, eating habits.

Thanks to a surge in the content of this substance in the body, a person experiences satisfaction and happiness when listening to his favorite music. He is happy if his favorite team wins a football match. Dopamine levels rise sharply at the time of sexual intimacy.

If there is not enough dopamine in the body, people are inactive, indifferent to studies, career growth, prone to depression.

However, the excess of its content in the body is far from safe. This substance increases the frequency of contractions of the heart muscle, raises blood pressure. long overuse dopamine drugs can lead to schizophrenia (the occurrence of auditory and visual hallucinations).

Note: The level of dopamine in the blood increases significantly with the use of alcohol, nicotine and cocaine, which increase its production several times. That is why drinking, smoking and drug use allows a person to experience a temporary feeling of joy and happiness, artificially enhanced. But the fact is that each time more and more of such a “stimulant” is required to get pleasure, and the abolition of its intake leads to the emergence of a “withdrawal” syndrome.

Serotonin

Hormone of happiness, antidepressant.

This substance affects the centers of the cerebral cortex, contributing to the emergence of optimism, a feeling of happiness, euphoria, and intoxication with one's achievements. The centers responsible for memory are also activated, cognitive ability. The action of serotonin on receptors spinal cord leads to improved coordination of movements, increased muscle tone.

The production of a substance in the body is enhanced under the influence ultraviolet rays, therefore, in the autumn-winter period, when the days are shorter and the lighting is mostly artificial, people often experience seasonal depression.

As you know, there are synthetic antidepressant drugs. Their action is based on an artificial increase in the content of neurotransmitter hormones in the blood, such as dopamine, norepinephrine, serotonin. In the treatment of depression and neurosis, they are taken for a long time. At the same time, there is a high risk side effects(impact hormonal substances heart, kidneys). With them misuse eye pressure rises mental capacity, there are sexual disorders.

Oxytocin

Enhances the pleasure of communication and intimacy.

Produced in the hypothalamus. Once in the blood, it spreads through the cells of the whole organism. This hormone enhances a person's attachment to their loved ones, as well as the desire to feel "one's own" in the team. He enjoys the handshake of a friend he trusts. For happiness, a child needs his mother to hug him, stroke his back, head. Massage has a calming effect on him.

This substance plays a special role in the female body. An increase in the level stimulates the onset of contractions, as it increases the contractility of the uterus. Thanks to oxytocin, the mother feels a sense of reverence for her child born in agony, and he instantly calms down when he grabs the nipple and draws out the first portions of colostrum. So mother's hormone gets to him, mutual affection arises.

Adrenaline is an anti-stress hormone

It is produced at the moment of extreme danger. At the same time, a person is able to instantly mobilize, forget about pain and fear, take risks for the sake of his salvation. His pulse quickens sharply, that is, blood circulation accelerates. Pupils dilate, so he sees better, hearing becomes more acute.

Norepinephrine - the hormone of peace and tranquility

Formed from adrenaline and helps to reduce blood pressure, relieve spasms and normalize breathing. The person calms down, and his mood improves. The formation of the hormone is facilitated by listening to quiet pleasant music, being in nature, contemplating the seascape. The less norepinephrine, the more adrenaline and the anxiety associated with its presence.

The role of sex hormones

The most important role in the body is played by the sex hormones estrogen and testosterone, due to which men and women have external features. These substances are produced in both sexes. But in the female body there are ten times more estrogen, and in the male body - testosterone, which explains the peculiarities of men's behavior, their physical endurance, and sexual activity.

Estrogens

In women, estrogens are produced in the ovaries after the onset of puberty. If there are enough of them, the girl develops correctly, her breasts are formed, her hips increase. beautiful figure, good hair and skin, gentle voice give pleasure to any woman. Thanks to estrogen, she is sexually active, fertile, and arouses interest in men.

If there is little estrogen, it worsens appearance, happening rapid aging body, menstrual disorders occur.

Wanting to prolong youth, enhance sexuality, some women take synthetic estrogens, risking their health. Hyperestrogenism causes infertility, the occurrence of tumors of the genital organs and mammary glands.

Testosterone

The presence of a small number male hormone in a woman's body makes her independent, confident in her rightness and uniqueness. At the same time, a “strong” woman remains fragile, tender and easily vulnerable.

There is an expression: “Men rule the world, women rule men, and hormones rule women.” loving man he will take this into account and will be indulgent to small “female weaknesses”. Excess testosterone leads to changes in appearance, voice and character male type, is a pathology that requires serious treatment.

Other Hormones Needed to Enhance Feelings of Joy and Happiness

You can name other substances hormonal action that can enhance the feeling of pleasure and happiness:

1. Vasopressin. It is involved in the regulation of the water-salt balance, which directly affects the condition of the hair and skin, the presence of signs of external attractiveness and health, pleasing to the eye.
2. Acetylcholine. Promotes development creativity, intelligence and memory. Thanks to him, a person is able to rejoice and experience a sense of pride and happiness when he manages to cope with a difficult task. Helps to maintain dignity, mental balance.
3. Melatonin is a regulator biological rhythm. Normalizes night sleep helping to fully relax after a hard day's work.
4. Somatotropin is a growth hormone. Increases muscle elasticity, improves the condition of the joints, prolongs youth. It is important to prevent its overdose in the body, since this causes such a pathology as gigantism. With a hormone deficiency in a child, he can remain a dwarf.

How to increase the level of hormones of joy in the body and feel happiness

Many preparations containing synthetic hormones of happiness are produced. Sometimes it is simply impossible to do without them. For example, estrogen-based products help in the treatment of infertility, as well as improve the quality of life by relieving the symptoms of menopause.

However, one must never forget harmful effects overdose. There are much more safe ways increasing the content of hormones of joy and happiness in the body and enjoying life.

The Importance of Proper Nutrition

With food, substances containing either hormones directly or substances that stimulate their production enter the body. Delicious and healthy food always improves mood. For example, to get rid of autumn-winter depression, you need to eat dark chocolate, fruits (especially leaning on bananas, pineapples, apples), drink coffee. They contain tryptophan, an essential amino acid involved in the formation of serotonin, melatonin and other useful substances. Tryptophan is also found in foods such as avocados, coconuts, figs, strawberries, and beans.

Tomatoes, kiwi, nuts, plums, eggs, meat, milk are also foods that need to be consumed to increase the content of joy hormones in the body. Everyone knows how sweets, baked goods, honey and other sweets have a beneficial effect on mood.

Consoling yourself with food, we must not forget that overeating is no less harmful than a lack of hormones of joy. A person who tries to suppress discouragement with sweets or cakes may develop obesity. The circle closes: eating sweets improves mood, but spoils the figure, which adds worries and stress.

Exercise stress

This is probably the safest and useful way improve mood and achieve happiness. Vigor of the body and spirit are inextricably linked. It has long been known that if the feeling of anger and indignation is bursting, it is useful to chop wood, do major cleaning or load yourself with other work.

long walk, physical exercise, jogging are a great way to take your mind off the worries. In addition, the body produces vitamin D during exposure to the sun, which accelerates the synthesis of happiness hormones.

Deep sleep

Dream - the best medicine from all diseases, including mental trauma. It gives strength, radically changes the mood in better side. No wonder they say that "the morning is wiser than the evening." In a sound sleeper, the content of serotonin, melatonin and other hormones necessary for recuperation increases in the body.

Doing what you love

Mental stress, achieving goals also require the body to increase the production of dopamine and other hormonal substances. Obtaining moral (and material) satisfaction is no less important for a person than other joys of life.

Sex and pregnancy

Sexual satisfaction, explosion positive emotions caused by intimacy Like nothing else, they stimulate the production of substances necessary for the appearance of a feeling of pleasure, happiness and love. The level of sex hormones, oxytocin, serotonin at this time is unusually high.

Nothing makes a woman as happy as the feeling of future motherhood. All experiences recede into the background. the main objective is to maintain one's own health and peace of mind required for normal development baby. During this period there is abrupt change hormonal background, increased production of substances necessary to maintain positive attitude. Pregnancy and love for a child gives a woman such strength that allows her to survive any sorrows.

In order to feel calmer, to feel the joy of life and happiness, one must make every effort to experience the love of loved ones, the respect of others. You need to set realistic goals and work towards achieving them.
