The future, it just keeps happening really.
Imagine if you will, that you have been in a horrific accident. You have had to have a limb removed, say your arm. The realm of prosthetics has advanced in leaps and bounds over the last few years. Work is being done on limbs that can tie directly into the patients nervous system, 3d printing is being used to mould custom facings and powered limbs are sensitive enough now to allow people to use them to pick up delicate objects with confidence.
