Been thinking a bit again:
Anyone here follow the NHL (National Hockey League). Remember several years ago they noticed guys were getting hurt when they ran into the goals? They decided that having break away goals would help cut down on injuries. BUT it did not work out that way. Well actually it did for a little while. But then the guys adjusted. Before they had worried about driving hard to the goal because you might hit the poles. Soon they did not worry about it. The odds of injury in each incident went down, but the increased number pretty much made up for it. Goal keepers were the big losers as they got run into a lot more.
Just wondering. Think kids with helmets just mught try to head wildly. After all the kid with the helmet isn't going to get hurt, right? But posts will still win and other kids will get hit in the face by the helmets.
Hopefully this will not trickle into my sport (Rugby) until my playing days are over, 20 or 30 years from now.
