There are many ways to keep it. First, those who are always on the go from morning till night should find time to relax because too much stress will affect their health. Second, enough time should be left for sleep because that will help one become rested and refreshed. Finally, regular physical exercises benefit one's health a lot. So one should always keep in mind that a certain amount of exercise is not a waste of time.
As for me, I like playing tennis in the morning. I also attach much importance to enough sleep and relaxation. I believe this will ensure my good health for the rest of my life
