Live long & prosper, friend, there's no time limit on life with CES, you just have to learn to live with it, not against it. I know - I'm learning too - April 09 injuries.
I can't walk very well right now- just a couple of feet because of a fall causing further spine injury, but it still doesn't slow me down much - gotta keep up with my kids so I 'roll with it in my manual chair! Good luck!
