what should a person do to stay healthy and strong?

have good nourishment and sleep.

healthy food,proper exercise and in good mood,don't be angry easily

I dont think there is a certain exercise or exercise program that is the best for staying healthy and strong. It has to be something you enjoy doing because lets face it we tend to continue on with enjoyable things. So find something that interests you whether it be walking, bicycling, yoga etc. And eat a balanced diet.I believe anything in moderation is okay. Its when we forget to draw the line on what is moderation and what is excessive that our bodies suffer. Be healthy and have a great day!

exercise regulary, such as jogging and also choose the right food

Yoga is sufficient for remaing healthy and fight from all illness problems. By doing yoga you can excercise your mind and body both. Then what you need if both are fit. So Do Yoga.

i think that getting enough sleep is the key to your over all health because if you dont get sleep, you end up being more able to get bugs and viruses. lack of sleep is the most harmful for your body.
