Every three weeks I get to hang around the Royal Free Hospital between blood tests, physical exam, scans etc that take a few hours of separate appointments. Not all locations in the building have enough signal to get an internet connection so I tend to work offline writing letters etc. This morning I'm short of offline jobs and only have the MacBook Air which doesn't have all my stuff on it, so here's a 2-minute quiz about electrics at the turn of the century.
