I love that you can see Marco’s tools in the background after his DIY thumb removal… It’s something I’ve always been interested in, but since the surgery on my leg I’ve been wanting to do a minor amputation more and more — my surgery caused some nerve damage so I have no feeling in part of my lower leg, and observing the different ways that my brain interprets it is just fascinating. I guess sometimes one is driven by fetishism, and sometimes by curiosity.

That said, I like having long opposable thumbs, so for me I think I’d go with a finger, probably the ring finger (I think Steve Haworth told me some time ago, when we were implanting the magnets, that if you’re going to mess with a finger, that’s the one to do because it’s the weakest, and even if you lose it completely it does not have a major impact on your ability to use your hand).
