It was fun growing up in sports where you could hit and throw you opponent. When you are young you don’t think about the after effects so much. It’s pretty clear our bodies our not designed to be thrown or it. In football, the one thing that always seemed silly when the players would hit each others helmets. It’s clear that there are some things that we probably not be doing. When you see this picture, it seems pretty obvious, maybe time to change the sport or do something else.
