We should look at this problem dialectically. Any problem must be split in two.

First of all, proper exercise for the elderly after meals is good for their health and can increase digestion. Because the gastrointestinal function of the elderly is degraded. Proper hiking can increase gastrointestinal peristalsis and help digestion. As the old saying goes, it makes sense to walk after a meal and live to be 99 years old.

Proper exercise can also reduce the incidence of hypertension, hyperlipidemia and diabetes.

But too much exercise is not good for your health. According to scientists' inference. The old man is over 50 years old. The daily exercise is between 8000- 10000, which is not the most suitable. Exceeding this range will increase the burden on both legs and cause synovitis.
