Good point on the weight of the ball.

I agree 100%.

My wife has suffered two mild concussions in the last 10 years. Both were the results of accidents (one from a car accident, one from a bad fall). She's now having some issues that the doctors believe are related. The issues are not as serious as former NFL players, but still, repeated blows to the head are repeated blows to the head. Whether it's a football/hockey player giving out a head shot, or a soccer player repeatedly heading a ball...or even just a blow to the head from accident - these are serious issues.
