Osteo arthritis cannot be reversed

it's a natural condition i.e. 'wear and tear' because we evolved up-right. Taking care of our joints is important but how many kids think about doing so, unless they are affected? JOA is extremely painful and limiting. I danced from age 8 until 18, we walked everywhere or cycled but I have to confess, I didn't run much .........
We are hunter-gatherers therefore on the move but not built for long periods of running. We ran in short bursts if the sabre toothed tiger was around

......... also we lived from dawn to dusk so our joints probably didn't get the 'work' that they have evolved to do

..... being a 24 hour society we expect more from our bodies ...........
