As a person who’s a paraplegic from a blood clot who uses a wheelchair and special devices to walk I can say at least he lives in a time where the technology is such that he can probably get a damn good prosthetic. It’s really difficult and very painful to try to use injured limbs, sometimes people have better function all around it they have the limb amputated and then use a prosthetic. Of course NOT being injured would be the best answer but that shipped already sailed poor dude.
