Contact Sport

I do not understand contact sports like rugby, rugby league or American football. Why would adult men want to throw themselves at each other to physically to prevent a ball from being taken to the other end of a field? Why would a sensible person accept battering, bruising and bleeding, or risk a broken limb to affect the result of a game. A game in which the winner is the one demonstrating the most intense use of force seems quite odd.

What are the spiritual affects of all this controlled violence? I suspect that rugby and American football are a refuge for warring and violent spirits during times of peace. They need a place to hide when the nations are not at war. I cannot think of a better place.
