@HesDeltanCaptain,
That is misguided malarkey. Why would you think to write such nonsense?
Many people have run as an exercise for decades with little in the way of health or other skeletal problems. Also, FYI, many primates run a lot of the time...some also swing through trees..but I digress
Mankind probably wasn't
ideally designed to run repeated ultra-marathons and marathons. I would give you that point. Eventually that sort of running can cause health issues..mainly in some joint breakdowns. However, running reasonable distances can be and IS very successful without causing undue stress and disability. Your way out of your depth here.
Once again, apparently you haven't looked at the date stamp nor read the previous posts. The person to whom your addressing, the OP, has been off the site for 4 years so you're not going to get a reply from her.
