Science does a pretty awesome job of letting the handicapped get around. Prosthetic limbs, electronic ear implants, there are all sorts of ways these people can live almost normal lives.
But some aren't settling for that, figuring that if we're using technology to make you walk, and technology is always improving, then why stop there? Why not make you walk better than those other assholes? Here are some technologies that within our lifetimes can make the human body better than what nature ever intended. Whether nature likes it or not.
5Replacing Missing Legs
More than once you've probably uttered to yourself "I'd give my right leg for another delicious piece of pie" but those of you who went to that one shady pie shop/human organ harvesting shop in Beijing know that's actually a bad bargain.
Fortunately, as with all technology, prosthetic legs have gotten better and better with time. Why keep trying to mimic nature, when you can just improve on it?
So, for instance, for those athletic types who have lost legs there are carbon fiber prosthetics called Cheetah Flex Feet, also known as blades. They're specifically designed for high-impact, legless insanity out on the track. As you may have learned in biology class, J-Shaped carbon fiber legs are not the same as regular meat legs and as such aren't subject to the same fatigues. So when a typical runner starts getting that old fashioned burning sensation in their shins, a runner on Cheetahs is just bouncing along like nobody's business.
How well do they work? Just ask Oscar Pistorius, a double amputee Olympian who was banned from the Olympics because his space-age legs gave him an unfair advantage over other runners. They let him take longer strides and use 25 percent less energy to run the same distances.
Of course they're not as useful in other situations, but, unlike your real legs, you can just swap these out with some others. Perhaps soon you'll strap on legs with artificial muscles made of carbon nanotubes, that even generate electricity as they flex. Sure, the designers claim that the whole electricity generation thing is so charging won't be as much of an issue, but we're assuming the real purpose is to deliver a nice electrical jolt with your roundhouse kick. Don't tell us there's no market for it.
