Nah, pain is for wimps!
Look, I have pretty bad arthritis in my feet from 30 years of fell running. Without painkillers, I'm hobbling in a few miles. Good old Ibuprofen helps me get around a 10 miler in reasonable shape. The damage is already done and if I want to further the knackering in the cause of enjoyment, why not? There's no point handing back the beardy fella a pristine unworn bod when your times up is there?
