Some people have bigger brains and harder heads than others... Then you have those with soft heads.
Take Tex Cobb, the boxer... That man never suffered a concussion in his life. I watched Larry Holmes beat his head for 15 rounds, turned his face into hamburger meat... The man lost but he never went down.
Then look at Eric Lindros... Great hockey player who suffered from multiple concussions... Or Sidney Crosby... Another soft-headed NHL player. Gordie Howe on the other hand likely never suffered a concussion in his 32 years of playing professional hockey.
If you suffer from concussions you should really try to find another job. Then again, I knew this dude who had 8 concussions, most of them while playing Lacrosse... Never got paid a cent... He played hockey and lacrosse for fun.
He's plays guard. Chances of concussion is pretty low at that position.
Remember “Dr. Lenkaitis”?
I was sad to learn he passed away in 2016.
