My grandmother is 79 years old this year. She loves her very much and can't bear to part with her. She went back to her hometown to find my grandfather in the summer vacation of 1 1, and then she got bronchitis because she couldn't stand the climate. Eat light, eat less salty. I don't know where you are. To find out what people in that place eat to resist endemic diseases. Also, people who live long should worry less. Let the old people live in peace of mind and don't worry about their children and grandchildren, so that they can live longer. I also suggest that you buy a book on Chinese massage, massage the elderly, be filial, but be gentle!
