Skating over long periods of time is honestly bad for your body. Studies show that if you have used a cast to treat a broken bone, it will up your risk for arthritis. Or honestly lets not forget the fact that skaters tend to fall usually 3 times in every hour of skating. That’s a lot for one persons body to handle and the long term affects show. Older people who have skated have either gotten surgery to treat the long term affects skating does to your body or have been in pain for a really long time. Or both. But all around skate is as addicting as tobacco so I don’t think me or any of the other skaters will learn.
