Good luck to you. I'm only 32 but am stiff as a board when I get up in the mornings from my back. When I have to lean over I do so sort of to the left side more and then forward. After about an hour of being awake, I loosen up. I have been to the chiropractor 3 times in my life and while my back feels wonderful after a "session", it remains stiff in the mornings. Guess all them years of helping everyone move and lifting up kiddos all the time does take it's tole.
...and on that day when my strength is failing, the end draws near and my times has come, still my soul will sing Your praise unending, ten thousand years and then forevermore!
