At what age do people start to age

At what age will people start to age? I believe many people would like to ask this question. If you age carelessly, it will definitely have a great impact on your body. The degree of aging must be controlled in time. Everyone will start to age at a certain age. Every year older, the degree of aging will increase. The older you are, the faster you will age. So at what age will we start to age?

Brain: Starts to age at 20

As we age, the number of nerve cells (neurons) in our brain decreases. When we are born, the number of nerve cells is about 100 billion, but it starts to decline year by year from the age of 20. By the age of 40, the number of nerve cells begins to decrease at a rate of 10,000 per day, affecting memory, coordination and brain function. Although nerve cells are crucial, it is the gaps between brain cells that are most degraded, said neurologist Wojtek-Rakowitz, a consultant at Imperial College Healthcare Trust in London.

Intestines: Start to age at 55

A healthy gut has a good balance between harmful and beneficial bacteria. Tom McDonald, professor of immunology at Barts and the London Medical School, said the number of friendly bacteria in our intestines starts to decline sharply after we reach the age of 55, especially in the large intestine. As a result, the body's digestive function declines and the risk of intestinal diseases increases. As we age, the flow of digestive juices in the stomach, liver, pancreas, and small intestine begins to decline, and the chances of constipation increase.

Breasts: Start to age at age 35

At age 35, breasts begin to lose tissue and fat, decreasing in size and fullness. From the age of 40, a woman's breasts begin to sag and the areola (the area around the nipple) shrinks dramatically. Although the risk of breast cancer increases with age, it has nothing to do with physical changes in the breasts. Gareth Evans, a breast cancer expert at St Mary's Hospital in Manchester, said that human cells are more likely to be damaged as we age, so the genes that control cell growth may mutate and cause cancer.

When people reach this age, they will start to age, and the whole body will age, including the eyes and nose. However, the degree and objects of aging are different at each age. People will have symptoms of aging at each different age. When they reach 50-60 years old, their whole body will age. Therefore, it is necessary to do corresponding maintenance to delay the aging of the body.
