I think that's a very good point. Unless we ourselves have had an injury like that, it is hard to say what we would be able to do/not do. I think it's far to easy to rule someone out on the basis of having prosthesis, maybe just thinking that the terrain would not be easy with a prosthetic limb, or someone might get stuck, etc. etc. There are quite a few people in this world with life-changing injuries, who manage to effectively compensate, learn new ways of doing things, and have some sort of prosthesis. This ability to adapt runs the gamut from activities of daily living, all the way to Paralympics, for some. IMO certain health issues should not rule someone out, by bias, unconscious or not. Same thing with heart, pacemaker, defib device. It always bothered me that CPH made a great show of pain/discomfort to avoid questions/deflect. My aunt had one. It didn't hurt. And I know someone with a prosthetic leg who could get around just fine. All MOO.
