My grandmother is like your father. She always takes a small stool with her everywhere. She has to sit down and rest before she walks a few steps, or she will be out of breath. "Three highs" is really one who has not fallen behind. Personally, middle-aged and elderly people are obese and have no benefits at all. Now it's not that it's hard to buy old people with money, but to lose weight. However, middle-aged and elderly people are too old to exercise vigorously, so safety should be considered first. It is recommended to take a walk instead of being thin. Standing? It's beautiful.
