Causes of aging

Aging is a natural process that everyone goes through. I believe everyone has noticed that some people age very quickly, while others age relatively slowly. Some people in their sixties look like people in their seventies. Not only are their faces full of wrinkles, but they also walk with a frail gait. Some people in their sixties look and act like they are in their forties. Everyone wants to age more slowly.

If you want to slow down aging, you must fight aging. The best way to fight aging is to prevent aging. We must develop good living habits in our lives, not staying up late, and develop the good habit of going to bed on time and getting up early. Don't smoke or drink.

A smile makes you ten years younger. Emotional stability is very important for endocrine balance. People with a gentle and tolerant heart are very beautiful. In fact, it is not just a psychological impression. Making a bitter face every day will cause skin cells to lack nutrition, making the skin on your face dry and dull, and wrinkles to appear, and will also deepen the "worry lines" on your face.

Regarding the mechanism of aging, there is relatively sufficient evidence for the "molecular cross-linking" theory and the "error-causing disaster" theory, which are closely related to genetic genes, as well as the intercellular substance theory that aging is caused by excessive accumulation of collagen between cells. Intercellular substances refer to substances produced by cells and secreted into cells or between cells. Such as hyaluronic acid, collagen, etc. Hyaluronic acid is a macromolecular substance that plays an important role in maintaining moisture in tissues. During adolescence, there is more hyaluronic acid, and the skin is moisturized and plump. But with aging, hyaluronic acid decreases and is replaced by collagen. Collagen not only lacks elasticity, but is also not easily decomposed, making it difficult for nutrients to enter cells and for cell waste to be eliminated. As a result, cell metabolism is low, ultimately leading to cell aging.

There are many ways to prevent aging, such as traveling and visiting various parts of the world to see the beautiful scenery. It not only broadens your horizons, but also makes you happy. Another thing is proper physical exercise. Young people can choose ball sports, while older people can choose walking, swimming, or attend senior citizen universities.
