You can have all the organ replacement you want. Once your drive train (feet/ankles/knees/hips, which ultimately impact on your spine) is shot, all you're gonna want to do is lie in bed.
I think a lot of actual real-life wheelchair-bound humans would object to your presumption of what they want to do.
I presumed nothing. Have you ever experienced sciatica or back pain from herniated discs so intense you piss yourself? When even breathing hurts?
If you are able to zing happily along in your Rascal Scooter and ignore the pain, my hat is off to you.
There's a lot of chicken counting going on when the future is discussed. We have very effective pain medicines right now that many people can't have because of their potential for abuse.
I wouldn't count on anything until you see actual meds on the market that some group of "We Know What's Best For You" people hasn't declared evil.
