Brendan Marrocco after his transplant. Source
This may be old news for some of you, but I just realized that we had the technology to perform arm transplants. I was reading an article about a war veteran, Brendan Marrocco, who suffered from a blast in Iraq in 2009, losing all of his limbs. Back in December he had transplant surgery that gave him two new arms. It may be a few years from now, but reportedly nerve growth will give him control over the new arms, and even some feeling. I think having real limbs could be much better than prosthetics.
