Depending on the age of the body, inevitable changes occur, which are not always visible even on photo flash mobs such as #10yearschellenge. How does the body actually change in 20, 30, 40, 50, 60 and 70 years?

From 20 to 30 years

In the period from 22 to 26 years, the skeleton ceases to develop, but in order to strengthen the bones, the intake of vitamin D and calcium is still necessary. Metabolism slows down, so you need to carefully monitor the diet, limit sweet and focus on body mass index, which should be in the range from 18.5 to 25. The body decreases the production of collagen responsible for skin elasticity, slows down the process of its renewal and sweat glands. At the same time, neural connections are strengthened, the frontal lobe of the brain, which is responsible for logical thinking, continues to develop; hormones are balanced after the transitional age. By the age of 30, the molar wisdom teeth grow (usually this process begins at the age of 16). By the way, they may never appear: because of the refined food, the need for wisdom teeth in modern man disappears and in some people they are missing even in the bud.

From 30 to 40 years

At this age, blood vessels gradually lose elasticity, pressure increases, muscle tone decreases - a person requires more serious athletic loads. The bone mass decreases, they become more fragile, but the bone tissue becomes denser. If a person leads a sedentary lifestyle, then the amount of muscle tissue is reduced and it is replaced by fatty tissue. This is the most successful period in terms of intellectual development: the person already has the experience and knowledge, less likely to give in to hormonal surges. At this age, men and women appear gray because of a decrease in the activity of the pigment-producing cells, melanocytes. The work of the salivary glands is slowed down, thanks to which the teeth are better cleaned, therefore, it is necessary to carefully monitor the oral hygiene. Collagen and elastin proteins lose moisture and are destroyed by ultraviolet radiation, while new ones almost do not develop, therefore, skin lovers have faster skin ageing.

From 40 to 50 years

In the fifth dozen of life, the human brain loses up to ten thousand nerve cells daily, and muscle mass - about 1-2% per year. In women, estrogen levels are significantly reduced, resulting in increased pressure. Due to slower metabolism, the body actively accumulates fat, especially in the abdomen. If a person is not well fed in previous years, then the process of deterioration of bones and joints can begin. It is at the age after forty who notice a noticeable deterioration in vision. It is especially important to continue to play sports for strengthening muscles and training the heart, aerobic exercise will do, but only after consulting with your doctor. It is not necessary to go to the gym: the scientific publication British Journal of Sports Medicine gives the results of an international study that showed that interesting sports games and various activities work just as well - you can practice tennis, badminton or dance, go to the pool, ride a bike and practice dancing

From 50 to 60 years

At this age, there is a high risk of disturbances in the work of the stomach and intestines, some have cataracts and signs of retinal dystrophy. The skin still loses its elasticity, but this process can be slowed down with proper care and lifestyle. Closer to the age of 60, cells of almost all organs of the body, including the brain, begin to break down; it slows down cognitive abilities and impairs memory. You can add food to preserve vision and memory to your diet, and sports loads must be matched to the capabilities in order to maintain and not undermine health. To strengthen the functions of the brain, it is important not to stop intellectual activities: read and acquire new skills, for example, prepare for previously unknown culinary recipes, learn to play a musical instrument or learn a foreign language.

From 60 to 70 years

Due to cell death, the work of receptors is dulled - a person is worse at recognizing smells, tastes and even temperature, some are cold in the heat or, on the contrary, do not feel cold. Closer to 70 years, the voice is changing due to the constant tension and stretching of the tissues of the larynx. It is important to continue to monitor the heart, undergo systematic examinations with the main doctors and monitor the weight. Physical activity can be reduced, long walks and swimming are perfect. However, despite noticeable external changes at this age, some people keep in shape and surprise with photos in bathing suits.

70 and older

In older people, the percentage of subcutaneous fat decreases, which is why wrinkles become deep and noticeable, and the skin becomes dry and flabby. Tissue regeneration slows down, scratches and wounds heal longer. Hair thinning and falling out, losing pigment. Diseases of bones and joints are common among people over 70 years old, and muscle mass decreases so much that a person gets tired faster even with low physical
