I regularly play football (soccer) and jog a couple of times a week for at least an hour. I occasionally experience soreness with my knees. I'm worried I might be doing long term damage. However, on the football field I see a lot of guys 10 - 15 years older than myself that can still run and plenty of them faster than me.
Is there any chance the impact from doing this type of exercise will be doing damage in the long term?
