Ah, well, I was thinking of my friend who had to have his whole right leg cut off earlier this year (I don't think stem cell surgery would work in that case!). When he got a prosthetic it seemed so oddly basic. Anything more advanced cost tens of thousands of dollars and was really not that advanced at all. I think TV and films have ruined my image of just how far along we really are technologically in regards to prosthetics. :/ (I said to him that I was expecting something with a built in rocket launcher. :P)
