On never give up. I don't know the story, but on a cruise ship as had a disabled passenger He too had no legs, one arm, missing fingers and no nose. One day he and his assistant missed the tour coach. As we were leaving he appeared and ran for the coach. I guess was mid 40s. He only used a wheelchair to give his legs a rest.
I have a friend, ex-SF, who can barely walk and needs a wheel chair from car to restaurant but insists on walking to the table. Sadly he is getting weaker but will not give up.
