I contacted various parents because I started to make up lessons on weekends. In my impression, there is an old lady with a very deep memory. When I first met him, he had sent his white-haired grandson to class. I felt very sorry for her at that time. At this age, you still need to take the bus to send your grandson to class.
Because my home is on the fifth floor, when my grandmother stood in front of me, she found that she was not panting as I expected, but talking to me angrily.
Later, I asked my grandmother's age and what she usually did. Grandma told me that because his son is divorced, he is now taking care of his grandson. If he is in poor health, then his grandson will not be taken better care of, so he insists on exercising in order to take better care of his grandson. In fact, he is 65 years old now. Although his hair looks gray, her figure is really good.
He said that because he is constantly exercising, he spends every day in the most active and healthy way. At first, he may still have some diseases more or less, but after several years of exercise, these diseases are gone, but he is getting healthier every day.
I think this is the charm of fitness. Fitness can make people live longer.
