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.
JESUS is LORD!
