Vegetarianism is not the reason why Andy Lau doesn't look old. Personally, Andy Lau's vegetarianism is not the main reason why he doesn't look old. From the perspective of modern medicine, long-term vegetarianism is actually consuming a person's health, because the balanced nutrition that the human body needs can meet our needs.
Strict self-discipline and regular work and rest are the important reasons why he keeps his young appearance. Personally, I think Andy Lau's strict self-discipline and regular work and rest make him not old. From his abstinence from meat and food at the age of seven to his recent age, he still has such a good figure, which shows how self-disciplined Andy Lau is.
With such a firm determination not to eat a bite of meat, few ordinary people can stick to it except those who really put down all their desires and escape into an empty net. They are greatly bound by their beliefs, and they can do without meat and only be vegetarian.
But Andy Lau is a vegetarian not because of his beliefs, but because he loves his wife. His wife didn't force him to be a vegetarian. So this shows how self-disciplined Andy Lau is. And a self-disciplined person, his life is often very regular.
Violating the laws of the body will accelerate our aging, and a short and regular routine is very beneficial to our health. When the body needs to eat, exercise and rest, it has its own specific rhythm. When this rule is not satisfied, it is easy to cause loss to the body. And live in full accordance with the laws of the body, then you can delay aging.
For Andy Lau, of course, he won't stay up until one or two o'clock every day, or even stay up all night occasionally, just like young people in our new era. As long as you stay in bed for a long time during the holidays, you never want to exercise.
This constant consumption of your body is of course easy to lead to short life and aging. Andy Lau's strict demands on himself, strict exercise and regular work and rest keep him in shape and keep his face young.
