How long does our body function last?

The human body is a complex object. Like a machine, each organ and part has an initial design life. If we can find ways to extend the life of our parts, we can reduce machine wear and failure. Studies have shown that the average life expectancy of Chinese people is around 76 years old, which means that our body’s shelf life is about 76 years. But do you know that every organ in the body is also in use? How much do we know about our body and how do we maintain our body organs?

Brain 20 years
The latest research published in the British Medical Journal shows that human brain aging may have begun since the age of 45. University College London has conducted a 10-year cognitive tracking survey of more than 7,000 British civil servants. Subjects ranged in age from 45 to 70 years. The comparison showed that the subject’s brain function generally declined. The time of brain aging may begin in middle age. The number of nerve cells in human birth reached 100 billion, but it has been decreasing year by year since the age of 20, and it has been decreasing at a rate of 10,000 per day since the age of 40! So at which stage are you now? Is memory, coordination, and brain function diminished?

How to protect the brain: The brain follows the principle of “use and retreat”, that is, the more you work, the better! The survey shows that people with more brains are 50% more intelligent than lazy people. Other studies have shown that the average life expectancy of mental workers is higher. Also remember to add more antioxidant foods rich in VC, VA, VE, etc., can effectively delay brain degradation. A good night’s sleep, healthy sleep helps promote the connection between nerve cells in the brain and delay aging.

In general, the ovarian function of women over the age of 35 will rapidly degenerate, and the quality of the egg will also age. At this time, the probability of abnormality in the fertilized egg division will be greatly increased, and the abortion may be caused by insufficient luteal function after pregnancy. In addition to the difficulty of pregnancy, the incidence of Down’s syndrome baby is also significantly increased.

Eat soy products properly. After women enter menopause, eating soy products can compensate for the reduced estrogen in menopause, thereby reducing or avoiding menopausal syndrome. If you insist on drinking a cup of soy milk every morning. Beta-cryptoxanthin helps protect ovarian function.
