Unfortunately, people will really become old and ugly at the age of 34

I don't know if you have this feeling:

In her 20s, even if I stay up late every day and irregular meals, the skin is still firm, fine lines and white hair are not obvious, like an apple that is properly maintained. After a certain age point, such as in his 30s, even if you have paid attention to health, people are still like the leaky ball, and quickly become dry and old. All came out.

I feel "faster" after a certain age, which is not your illusion.

A paper from Stanford University in the United States published in "Nature Medicine" pointed out that people are likely not to grow old slowly and at a constant speed. Instead, at the age of 34, 60, and 78, it suddenly collapsed.

Why are these 3 time points? How did this conclusion get it?

Human aging is not uniform speed

More than 60 years ago, scientific researchers found that in the age, another set of "aging clocks" were also hidden, and this clock seemed to be able to allocate back.

In 1956, Clive McCay, a biochemist and elderly patients at the University of Isaaconar, New York, did a bit terrible "courses symbiosis" experiment. They combine their vascular systems through surgery through surgery to share a circular system.

As a result, after 9-18 months of old and young mice, the bones of older animals are similar to the bones of young mice in weight and density. In other words, the bones of the old mice are "younger".

In the past many years, there are many similar experiments, especially in the field of aging. Researchers have found that, whether it is the heart, the brain, muscles, or almost all other tissues, the blood of the young mice seems to bring new life to the aging organs, making the elderly mice stronger, smarter, and healthier. Even fur is smoother.

Are there any laws of human aging?

When 34, 60, and 78 years old, why did it happen three times?

Is a woman really older than a man?

When you wake up every day to look in the mirror, you may be ugly by yourself. When you were a kid, you were often praised and lovely. It was the master of his uncle and aunt, but when he grew up, this face was disgusted even when he saw it.

Why do you grow longer and ugly?
