I have Observe Elderly male and females exercising on the hard court outside my house. They usually play music and exercise with a fan or sword. They usually do it in the evening when it is cooler. This is very calming and also helps the elderly to work out. It is not very stressful and very healthy for the elderly. There is a routine that they use and exercises about once a week. I think that the government should encourage such activities. They can encourage it by having such exercising events or carry such courses at a cheap rate or for free by the community centers.
