You gotta be a bit nuts to recover from serious medical situations.
A good physical therapist knows that there are some of us who have to be restrained a bit from overdoing the recovery *but* that we are also the best rehab cases 'coz we are *motivated*
My experience is that my community know that when they see me on my bike I am *well* and *happy*. They *like* to se me recovering against odds.
I think people like to see someone *really* recover. People love a fighter who will never say die. It gives the courage too and also they tend to prefer to support a fighter, rather than pity someone who is sidelined for ever.
Go for it!

ps sorry about all the *'s for emphasis, this is one thing I really get on a soap box about
