Generally speaking, the common health care method for middle-aged and elderly people is to do some moderate exercise, such as Tai Ji Chuan, Wuqinxi and walking. At the same time, they will drink more water and be picky about their food choices. Generally, I will eat some fresh fruits and vegetables, some junk food or meat food, but I will not eat them, and I will also eat some meaningful Chinese herbal medicines such as Lycium barbarum or ginseng.
