Do some simple health activities without too much financial support. For example, to ensure a regular work and rest and sleep for about 8 hours every day may be a little longer for the elderly, because the sleep quality of the elderly is not good and needs to be extended. Then, we must ensure that the mood is calm, not too happy, not too angry, because too many emotions will affect the secretion of hormones in the body and affect the state of the body. Proper exercise every day, whether it is walking or running, can play a role in keeping in good health and has a good effect.
These activities mentioned above can play a role in keeping in good health, but they don't need too high economic cost. Running, just looking for an open space to run and sleep, is an activity we have to do every day. It is enough to have a bed to control our daily life. In terms of diet, try to be light after old age, eat less greasy things, or don't need too much economic knowledge. What we should pay attention to is the change of living habits, not the financial support. If we have money, we can make our physical condition better, then the activity of health preservation will not be widely promoted.
Keep in good health, and the sooner you start, the better. Even young people pay attention to regular work and rest every day, keep a good mood, and then pay attention to proper exercise, which is also very good for their health. Even if they don't show it now, they will show it when they are old, because the higher the bone density when they are young, the less likely they are to get osteoporosis when they are old. This is a very simple aspect.
