My impression reading the posts here on this board is that most of the posters are elderly, in the 60s, 70s, or over, giving credence to the notion that the mechanism of damage is statin use exacerbating age related depletion of coenzyme q-10 levels.
I was thinking a poll might be useful. Me, I'm in my very late forties and my difficulties are fortunately comparatively mild compared to some I've read on this board.
