I'm not sure who came up with it first, but my father-in-law says this all the time: "Pain is nature's way of telling you to slow down."
Here's my corollary: A ruptured disc is nature's way of telling you that your purse/briefcase/diaper bag is too heavy.
I have slowed down so much as to be indistinguishable from a corpse. Gives me a chance to read and do other things I always want to but can't. Like make up stupid limericks:
There once was a gal with a cane
Who said, "I am tired of this pain.
It keeps me in bed
And on powerful meds,
Which prevent any use of my brain."
Looking forward to more lucid times.
