Almost every sport has a 100% injury rate where you eventually get hurt bad enough you can't play anymore. The trick is choosing a sport where the most common injuries prevent you from playing the sport but don't prevent you from walking. A good percentage of swimmers eventually develop shoulder injuries, but (AFAIK) that doesn't prevent you from doing anything except swimming.
I have played hockey for many years and know quite a few people who have done the same. I can't think of anyone with a long term injury.
I suppose it is reflected in 'old timer beer leagues'. There are a few 50 year old guys on my team right now, and they can play fine they are just slower. Sames holds for baseball.
Even though football isn't that popular here - most of the guys I know that did play with hopes of making it big in the US college system ended up injured.
That isn't true. It is rare that you would break a leg playing basketball or any bone at all playing baseball. It happens all the time in gridiron football. I wish I could find the chart where I got this information. The strange thing was, if I remember correctly, that the 2nd worst sport was women's soccer, because so many people tore their ACL.
"It is rare that you would break a leg playing basketball or any bone at all playing baseball."
I read somewhere that a lot of baseball players will just call a cab if they have to walk more than a block or two because their ankles are so shot. Not sure if this is true or not though.
