What scientific or medical breakthrough do you most want to happen in your lifetime?
TIME TRAVEL. For serious. Mostly for money and political gain. Also because I'd want to go to one of those American Doctor Who cons they had back in the 80s, back when most of the major cast were still alive... It'd be weird but I'd place bets on how the series will end, then go back in 1989 to collect my winnings.
Also, new hair! Taken via the magical medium that is my webcame because I left my camera in Oldham. Smooth.
