You grow old long before wrinkles

French doctors have found that sperm quality begins to deteriorate from the age of 35, so when a 45-year-old man is one-third of the pregnancy will lead to miscarriage.

Here is the time when different parts of your body begin to lose in the battle with time:

1. Brain: Starting to age at age 20.

As we get older, the number of neurons in the brain decreases. We start with about 100 billion neurons, but at the age of 20, it starts less. At the age of 40, we lose about 10,000 neurons a day, affecting memory, cooperation and brain function.

2. Bowel: Began degeneration at age 35

A healthy intestine has a balance between beneficial and harmful bacteria. But the amount of beneficial bacteria will be significantly reduced after age 55, especially in the large intestine. As a result, we digest less and increase these organ diseases.

3. Chest: Start getting old at age 35

In the mid-30s, women's breasts begin to lose tissue and fat, reducing size and plumpness. The sagging phenomenon starts at age 40 and the nipple shrinks significantly.

4. Bladder: Began damage at age 65

Loss of bladder usually occurs when you reach 65 years of age. It starts to shrink suddenly, even when it's not full. Women are more likely to experience this problem. The bladder's ability to hold urine in an elderly person is only half that of a young person, about 2 cups at the age of 30 and 1 cup at the age of 70. This makes older people more urinate, and easier to urinate infections .

5. Lungs: Began degeneration at age 20

The volume of the lungs begins to slow down gradually from the age of 20. At age 40, some people actually suffer from dyspnea, which is caused by the rib muscles and cavity that control breathing hardening.

6. Voice: Old age from age 65

Our voice becomes smaller and hoarse with age. The soft tissue in the cavity sounds weak.

7. Eyes: Begin degenerating from age 40

Glasses become popular with many people in their 40s, often by farsightedness. As we age, our eye's ability to concentrate is poorer due to weaker eye muscles.

8. Heart: Old age at 40 years old

The heart pumps blood less efficiently around the body as we age. Men over 45 and women over 55 are at greatest risk of heart attacks.

9. Gan: Start spoiled at age 70

This is the only organ in the body that seems to defy the usual aging process. If a person does not drink alcohol, smoke or has a contagious disease, one can transplant the liver of a 70-year-old man to a 20-year-old.

10. Kidney: Depression from age 50

The number of units that filter waste from the blood begins to decline in middle age.

11. Bone: Old age at 35 years old

Until the mid-20s, bone density still increased. But at the age of 35, bone loss begins as a natural aging process.

12. Da: From the mid-20s

Do not think that when there are new wrinkles on the skin, we gradually reduce the production of skin adhesives from the mid-20s. The replacement of dead cells also slows down.

13. Fertility: Decline from age 35

The ability of women to give birth begins to decline after age 35, as the number and quality of eggs in the uterus decreases. Men also began to lose their fatherhood around this age.
