I thought I might chime in. I'm only 49, but...

I mentioned somewhere on this forum that I blew my back out about six weeks ago. Just putting a piece of wood into the stove. Not a huge piece mind you, it is a small stove.

Anyway. Yesterday I picked something (small) up by BENDING AT THE WAIST!

How amazing is that, huh?

One change I made recently, and I can't discount its significance; correlation not indicating causation and all: I completely stopped drinking soda (mellow yellow) and started drinking local bottled water (lots). I feel better over all.

Anything to do with the back doing better? Who knows.

Moral is: if you're trying to heal, every bit counts.
