Not the inherent risk, but what the game is built upon, Fern. Football is purely built on violence, unlike riding a bike, or roller-skating.
Well, you seem to taking a slightly different tack here; you're mentioning traits such as "violence, collisions, and destroying your opponents" that you appear to find undesirable. But then you're dismissing traits football has that the others may not, such as discipline, teamwork and physical conditioning, that most people would find desirable.
I was addressing only the aspect of injury. I played football for many years, but my most serious injuries were from other activities. I got a real dandy of a concussion from motocross racing and a serious shoulder injury from snowboarding.
My point is simply that there are many activities that people engage in where injuries can be expected to occur.
Ok -- how can you play pro-football in a "safe way"?
Shrug, it probably can not played in an entirely safe way, but neither can many other activities I mentioned.
I don't know what will happen with football. When trying to do a trick on a skateboard etc when you're injured it's pretty obvious because the bone is sticking out of your leg and you know to stop. Concussions
can be a bit different. You may not realize that you've suffered one and may continue playing like the skateboarder who bangs his shin (or head) yet keeps at it.
The retired football players now reporting brain damage played under different rules and circumstances. There were no rules on 'head hits' and when they got concussed they went back out and played as soon as the 'cobwebs' cleared. Maybe the new rules and equipment will prove sufficient to negate most concussion injuries. Also, used to be that a knee injury meant retirement, maybe in the future a certain number (say 3) of concussions will too.
