While I primarily follow hockey, I know other sports with the NFL being the leader with it comes to contact to the head and concussion like symptoms and their long term affect on the players.

Last week, a Boston university that did the autopsy on Derek Boogaard's brain found signs of early dementia possibly from all the fights that he was involved in during his professional career NHL and minor league.

It's been documented that there are mid 30 year old football players who have dementia and had history of head trauma. It was so bad for one former player, that he took a shot gun to his heart and pulled the trigger after he pinned a note to himself asking to send his brain for autopsy.

We know Boxer's have this problem too since fighters are trading blows to each other, and at times they are at the head.

So what other sports should we be concerned about having this problem? And I am not talking about accidental collisions like 2 players running into each other.
I've heard someone mention soccer when players are heading the ball.

And how long do you think we will see massive changes in sports as we know it because of liability/genuine health concerns to the players?

As a kid growing up playing hockey, it took a few kids who became paraplegics before rules changes and advertisement campaigns were made to educate and enforce no hitting players in the numbers.

To be honest, as a Vancouverite, I am still bitter that the league dropped the ball on the Moore hit on Naslund. Pat Lafontaine, Paul Karyia, Eric Lindros is just to name a few superstars who's career changed after suffering their first concussion.
