I had a ruptured disc in my back in 2001. It's the absolute second worse pain I have ever dealt with. I wouldn't wish it on anybody. Having the pain WITH accompanying numbness is somehow worse than just the pain.
Seeing as how both my parents have had issues with disintegrating bones in their back (and most likely I'm going to get it due to heredity), I second what StaggerLee said - I wouldn't wish it on anyone.
-Flair plane accident- The very scary tale of a private plane that went down in 1975 with Flair, David Crockett, Mr. Wrestling, Johnny Valentine and Bob Brueggers. Flair mentions how it didn't humble him at all at the moment but does now thinking back.
