First of all, for the elderly, you can choose some dance, because this way the amount of exercise is relatively small. And can effectively exercise to the strength of the whole body, can let oneself in a have a calm mind.
Second, the elderly try not to choose some strenuous exercise, such as some long-distance running or fast running. There are also some ball games that are very intense. You can choose some more gentle exercise, such as swimming and so on, or walking.
Thirdly, you can also choose some chess sports, because the internal movement can exercise a person's brain. It can help you to think positively, and it can also help you to make some friends, and then we can discuss some games together.
Finally, you can also choose to travel to some places to increase your insight. But try to choose some city tours, such as going to some museums and so on, or going to the library to read books, which is also a very good program.
Like I plan the exercise and life of the elderly, that is, you can do some dancing or singing, and then some times you can also take a walk and do housework. Another thing is that you can also make some new friends and broaden your horizons.
