Human aging is an inevitable biological process. The jokers claim that a person begins to age from the moment of birth, but in fact, the first signs of aging of the body appear in the period from 30 to 40 years. From that time on, we will follow the development of our body, what changes in it occur over the years.
Signs of aging in a person 30-40 years old
• For most people of this age, fat begins to concentrate in the abdomen.
• In women, the ability to fertilize is reduced and there is a risk of abnormal intrauterine development of the fetus.
• In men, testosterone levels drop and baldness may begin.

• Although some 40-year-olds are “just beginning,” physical functions begin to weaken at this age. Metabolism slows down, a person's weight gradually begins to increase. The hair of both men and women becomes thin and gray, the level of sex hormones in the body decreases.
• In men at this age, the prostate gland is enlarged, and this is one of the main sources of "male" problems.
• In women between 45 and 50 years of age, menstruation ceases, menopause occurs, which means a loss of the woman's ability to fertilize. The level of estrogen in the body decreases, and this can cause hot flashes and other unpleasant symptoms. In addition, at this stage of human aging, the content of calcium and other minerals in the bone tissue decreases.
Aging of the human body 60-80 years
• From the age of 60, visible aging of a person begins. The skin begins to sag, wrinkles appear. Muscle dystrophy occurs due to a decrease in collagen content in the body.
• In both men and women, bone density decreases, but in women this process is more intense. By the age of 70, a woman's bone density is two times less than it was at 30.
• The walls of the arteries become thicker and less elastic, which increases blood pressure and greatly increases the risk of heart disease.
• Most people experience hearing and vision impairment.
• The functions of the brain and other organs are weakened.
• The immune system is no longer as efficient as possible, and short-term memory may deteriorate. Usually people at this age lead a relatively active lifestyle, but their opportunities are significantly limited.
