Have you ever experienced being the best in a group? It is nice to have people look up to you. You feel good about yourself. It seems like you are on top of the world. That is until you are faced with a difficult challenge that is too much for you to handle. It is then that you realized that you have no one else to turn to. You have to come up with a solution to the the crisis on your own. You have to bear the responsibility for the whole group.
We are all aware how our health suffers from a sedentary lifestyle. That is why we need to incorporate exercise into our habits so we keep our body healthy and we can function at our best. The same is true for our brains, after all the brain is also a muscle and just like any muscle that is not exercised, it will deteriorate in the long run.
