I read this somewhere and found to be absolutely true. In you age, we all want to make money and so don't care so much about health, start saving money. Later on when we are not that healthy, we withdraw from the same savings to take care of health. So be after money so much early in life, let us be after health also. Taking care of health while young is an investment and pays dividens in the older age. There is no insurance that can replace that dividend. So let us work on it. I try to go for walk everyday even when i get up late. It really refreshes me and i am sure you will be having your own physical activities to do refresh yourself.
