Wouldn’t it be great if humans could just, regrow any lost body part? I mean, it would completely change the way we think about safety! Extreme sports suddenly may not seem as extreme, because well, there wouldn’t be as much of a risk of permanent injury! Come to think of it, now that we are saying all of this out loud, it sounds like the exact superpower of everyone’s favorite Xmen, Wolverine! Now there’s a guy who has it all. Looks, brawn, charm, and of course, the ability to heal at an incredibly fast rate. But let’s bring this back to reality why CAN’T we do this? I mean, we can certainly heal after cuts and bruises. And we can even recover from something like a broken bone, or a torn muscle. But why can’t we regrow a full limb? The fact that salamanders can regrow not only their limbs, but tails, and even their spinal cords, makes it all seem like it SHOULD be possible! Well Brainiacs, that’s exactly what we are discussing in today’s video. We’ll go over not only the natural healing processes of humans, but why we can’t regrow entire limbs like our buddy the salamander. We’ll also shed some light on exactly what happens when we do lose a body part like a finger for instance and how doctors reattach them. We even have a story of one man and his transplanted arms. It’s a crazy, but very real area of science Brainiacs, and we can’t wait to share it with you, because even though the healing powers of Wolverine are out of our reach, we still have quite a few amazing options available to us to get us up and running again!
