4. Be Sociable Whilst Being Outdoors

When in college or school, you will find that this becomes a lot easier. You need not have to go to the cinema or watch movies with friends all the time. Even in winter there are things that you and your friends can do outside. Even if you decide to go for a walk to the pond, you will feel the benefits of a healthier lifestyle. You are going to spend time with your friends anyway, so why not do something that is good for you.
