Health care has been a good virtue habit since ancient times. Medical care can bring us a high quality of life. For example, does the old lady cook a lot of whole grains, which can regulate people's health? Health preservation can be said to be a good living habit, which needs long-term persistence, and it is not an overnight thing. As young people, we should not blindly oppose the elderly. What we have to do is to help the elderly distinguish. For example, some health care products or medicines are actually sold in the name of health care, and we need to pay attention. In fact, the health viewpoint of such programs is correct, but its motivation is not so simple. They are more about making profits for sales. We can learn from his concept of health preservation, just don't buy his things, haha.
