Running

Running is an extremely unique physical activity, really like none other.  One just goes out there, and starts to run.  As the distance wears on the runner, he is tested on his physical and mental endurance.  It is interesting, however, how much more running is mental than physical.  Yes, some physical strength is necessary so there is no passing out, or extreme medical conditions, but the pain that is felt can be completely subsided by the power of the mind.  As long as the brain is focused on the fact that the pain is not really there, it will and eventually does subside.  That is interesting because so many people are terrified at the thought of running a mile, when in reality, I think a lot of people could do it.
