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.
4Curing the Blind
Next to death, blindness is what most people fear the most. Yet all of us are just one nailgun accident away from saying goodbye to our vision forever. But thanks to science, soon not only will you not need to go tapping around with a cane or beg for change on the street cartoon-style, but will have Terminator-style computerized vision with data overlays.
Thanks to a Virtual Retinal Display technology, they'll have a device that can project the image through whatever tiny part of your eye remains undamaged (and eventually they'll be able to connect directly to the optic nerve itself, in case your whole eye was plucked out by a bird or something).
The visual display that feeds into your brain can actually be sharper and brighter than what your God-given eye brings you, and can even reduce glare in ways a natural eye can't. As an added bonus, why settle for just having vision restored when VRD technology can overlay an image displaying information about whatever you're looking at?
What kind of information? Use your imagination. Give the device WiFi access and it could presumably look up any damned thing you want. Maybe you can see a dude on the street and it'll run an instant background check in the time it takes him to get within mugging range. Or maybe you hear a song on a passing car radio, and it'll pop up the title and artist.
This isn't exactly science fiction, either; already they're working on VRD displays for non-blind people that can, for instance, let a mechanic look at an engine and instantly get an inside or exploded view of the mechanism. Your surgeon could do the same, seeing a 3D image of your pancreas all while displaying vital stats. Or amusing Twitter updates. Whatever.
