In my opinion, square dance is a social way, which is good for the elderly physically and psychologically. Psychologically, they can make more friends. It is a pleasant problem to have activities with like-minded friends. It's the same regardless of age.
If the elderly don't go out to socialize, they are actually lonely every day. It doesn't matter if you have grandchildren. If you don't have grandchildren, do housework at most. When you are old, you can't do any heavy work. Then watch TV. Children are working outside the home, and they have the heart of companionship, but they can't put it into action.
I still remember that there was a public service advertisement before, which was to pay more attention to empty nesters. In fact, it reflects a social phenomenon. According to statistics, there are more and more elderly people suffering from depression.
But since they organized these square dances and Tai Chi, these phenomena have improved, so I think it is good for the elderly to have their own social life.
Of course, square dance is also an exercise for them, and the effect is very good. My mother used to be a fat man, but she was too old to do other high-intensity sports, so she had to dance and gesture. Hey, I'm really losing weight.
I think she is energetic and healthy now. So in reality, square dance is still very beneficial to health. Even if it takes up public places, these can also be coordinated. I hope there will be more places and more activities in the future, so that the elderly can have a richer old-age life.
