IN these pages we’ve featured plenty of stories of people who’ve lost an arm and had to have a prosthetic replacement. But now one scientist is saying that even people with two working arms could still use a third one.
Professor Silvestro Micera believes that third-arm control is no longer a thing of the future. He made a presentation last week at the annual meeting of the American Association for the Advancement of Science, titled From Science Fiction to Reality: Can We Control More Than Two Arms?
He thinks that in some jobs or situations, having an extra arm could be very useful, allowing people to carry out more complicated tasks, hold more equipment, or just do their job more efficiently. Our first thought was that we could play PlayStation and still drink a cup of tea, but we’re sure there are many more useful situations.
For instance, a surgeon might be able to work faster and save more lives if they have an extra arm, rather than having to ask an assistant to hold something or move something out of the way.
What do you think? Would a third arm be handy, or too weird? Take part in our poll and let us know what you think!
