For me this question is quite difficult, I think I would prefer not to have legs and move around with a wheelchair or something like that, since not having arms would make it impossible for me to do so many things, like eating without help, being able to use the computer, being able to move things and so other things that seem normal but that not having arms is impossible, not having legs is not nice either, but I think it can be handled better, whichever you prefer.
