Lift with your legs, they taught us.
My knees are worn to, bone against bone, for it.
Very lowest part of your back, gets the other part of the load from leg lifting.
Arthritis in the low back from that. (grimmaced swear words go here)
I've put off having the knees replaced because I figure there's gotta be someone working on a replacement epoxy or some such thing, to replace that missing cartilage.
As a 'Baby Boomer", I'm old enough to not quite be just horribly worried about cancer or who knows what the heck else, from being a test case for a new type of " knee repair kit".
hmm.. Maybe I oughta be searching alibaba-bay for set?
