Yep, left knee blown out long ago and toast, no new one for it as the crooked ankle makes it a no go, right knee has taken the brunt of the work load as the left couldn't be trusted.

Right one took a couple of serious falls/blows a couple of years ago and became the "bad" one, ef me.

Realized it wasn't going to self correct as it normally does so started collagen, calcium, magnesium, vitamins, etc. and snake oil g*d awful expensive Instaflex.

It all made a big difference and has helped keep me riding, working on the cars, house, yard and all else, also retired a year ago which of course helped but wasn't really what I wanted.

So here I am, could be a lot worse and probably will be down the road.
