I was just wondering, what are some bad effects that result from running? I know that it can damage your knees, however, what other effects can running have on your body that are detrimental?

I guess it depends where you run. if you do it on the treadmill it doesn't affect your legs that much like if you did it outside

I've seen a lot of runners with messed up toes and feet too. But I think it all depends on how much you do. I've only just started running one day a week and my one knee is hurting already and I got tendonitis once too, but I feel like if I keep going I should eventually be in shape and then have less problems.
