I wonder if this has neuroplastic similarities with some research (too lazy to find it right now) on using non-dominant hands for operations like brushing teeth?<p>Perhaps we should all practice walking down stairs while holding a rather full glass of wine as we get older (then chugging it triumphantly if we reach the bottom without spilling it)?
I wonder if you could get a similar effect from using a mouse. We know how compelling computer use can be and if that could offer a similar benefit then that would be amazing.
