I've never enjoyed running and never practised it on a regular basis. I have chondromalacia which started (or rather had been diagnosed) in my early twenties.

I've never enjoyed running and never practised it on a regular basis. I have chondromalacia which started (or rather had been diagnosed) in my early twenties. It doesn't prove anything of course, but probably some people are inclined to get joint problems anyway (although running might make it happen quicker probably).
