Healthy lifestyle. What is it like? I think first of all you should eat healthy food - fruit and vegetables, fish and meat. Also you should drink much water. Of course Physical exercises are of great help. You have to train regularly to keep fit. Try to spend two hours a day outside. You can invite your friends to play some games with you such as volleyball for example. And keep calm. Try not to be nervous because it can course any pain or illness. I believe healthy lifestyle is in your mind. If you really want to be healthy you will find all the ways to get it.
