Men: From 35 years of age or more, the facial skin starts to show signs of aging such as: dryness, roughness, facial muscles loose, not firm, facial features are not clear.

Lung

Females: 20 years of age begin to show signs of weakness, in some people there is also a phenomenon of shortness of breath, shortness of breath or asthma.

Men: When 30 years old, men breathe 946ml of air / breath. However, by the age of 70, this figure dropped to 473ml.

Brain and nervous system

Women: began showing signs of aging of this organ at age 22. Neurons in the brain tend to decrease. After age 40, neurons will gradually decrease by about 10,000 cells / day, thereby affecting memory and brain function.

Hair

Men who turn 30 years old begin to show signs of white, women above 35 will have this sign.

After 60 years of age, the number of hair follicles is less, the hair gradually falls out in large quantities. The reason that the hair is black is because there is a special melanin in the hair, the body does not have a separate gland secreting this melanoma, so the black melanin produced in each hair is not the same. each other, resulting in black hair, white hair in a common body.

Chest

This part begins to show signs of impaired functioning at age 35. Along with the amount of estrogen and female sex hormones, which tend to decrease, the breasts gradually weaken function and deformity. After age 40, the nipple shrinks very quickly.

Muscle

30-year-old begins to weaken the function of function and aging. The muscles are constantly formed and degenerated, forming and then degenerating again. After 30 years of age, the speed of decline, deterioration faster than the speed of formation. After age 40, the rate of new muscle formation will decrease by 0.5-2%.

Bone

The part that accounts for most of the body's weight starts to show signs of weakness when it turns 35. The thickness (density) of the bones before the age of 25 is constantly increasing. However, up to 35 years of age, bone quality gradually decreases, entering the natural aging process. When 80 years old, height can be reduced to 5cm.

Heart

40 years old start aging. Along with the aging of the body, the ability to squeeze blood for the whole body decreases. The incidence and development of heart disease in men over 45 and women over 55 are quite high.

Teeth

40 years old, teeth begin to degrade function. This is also the time when saliva flow will decrease. Saliva can wash away bacteria. The amount of saliva reduction and gums reduces the risk of decay.

Eye

40 years old with strong signs of aging. Looking at objects at close range is extremely difficult. Next, the ability of the eye to adapt to the type of light is reduced, extremely sensitive to light rays with strong intensity, difficult to drive at night.

Kidney

50 years old began to weaken function. The filtering function of the kidneys begins to weaken at age 50, resulting in the body losing its ability to retain urine, always in need of toileting. In people 75 years of age, kidneys work only half of people at the age of 30.

Prostate

50 years old start aging. Prostatic fibroids also lead to a series of endocrine problems in the body, most men over the age of 50 suffer from this disease. The prostate in the normal state is quite small, but when there are signs of fibrosis or aging, it can be several times larger than normal.

Hearing

Over 55 years of age begin to show signs of hearing loss, hearing loss significantly. The majority of people over 60 years old lose their hearing due to aging. That is called deafness in the elderly. Thickening of the eardrum makes it difficult for the elderly to hear high-frequency sounds.

55 years old began to show signs of aging. A healthy intestinal tract has the ability to balance its functioning with harmful and beneficial bacteria that enter the body. The number of beneficial gut bacteria decreases rapidly when it reaches age 55, which is most often seen in the large intestine. As a result, the body's digestive function decreases, the risk of intestinal diseases increases.

Tongue and nose

The 65-year-old began to decline in function, becoming increasingly hoarse. The cause is due to the soft tissue organization in the throat ' to the old ', affecting the level of chime of the sound when emitted.

Women's voices tend to be hoarse, the sound quality decreases, the volume becomes smaller and smaller. In men, it is getting weaker and weaker, the volume is getting higher.

Bladder (bladder)

65 years old start aging. At this age can lose urine control function, frequent urination, continuous. At this point, the bladder suddenly shrinks even when the amount of urine is not fully occupied.

If the 30-year-old bladder can hold 2 parts of urine, when turning 70, this number is reduced by half.

The reduced ability of the bladder to lose will lose the ability to control urine in the body and cannot excrete all the remaining urine in the body, thereby leading to the risk of intestinal infection.

Women: the majority of women in their 55s have vaginal atrophy, vaginal dryness, loss of elasticity, making 'love story' a torture.

Liver

70 years old start aging. It seems that the liver is the only challenging organ for the body's aging process. The ability to regenerate liver cells is extremely strong. If a small part of the liver is removed after surgery, 3 months after the liver will develop normally, complete all functions.

If a liver donor does not smoke, drink alcohol, and have no genetic disease, the liver of a 70-year-old can be used for transplanting for a 20-year-old young man.
