After multiple concussions playing the game of football
Troy Polamalu continues to play the game.

When is enough enough? When you can't function as a human being anymore? When you eat your lunch through a straw, is that when you quit?

Hines Ward thinks about it. He worries about other players when he sees a hit taken helmet to helmet or helmet to leg etc..

Tim Tebow took a hit helmet to leg on September 26th but returned to play on Saturday against LSU, a game they won.

Tony Polamalu has had 7 concussions since high school.

Safety Ryan Clark says, "We play because we love it." What about the wife, kids, family, your life? Don't you love that too, Ryan?

When football is over, what will your life be like? Football players retire at a young age, old for football, but at 36 and retirement is inevitable, the rest of your life looms ahead. How would you like to spend it?
