Nigel Ackland is a 53-year-old father who lost his arm in an accident six years ago. Now, thanks to a high-tech bio-hand so precise he can type, he’s finally something close to fully recovered. Nigel controls his not-entirely-un-Terminator-like carbon fibre hand with movements in his upper arm and little tiny muscle twitches it knows how to react to. I just hope he’s still on our side when the uprising comes.
