Born in Stockholm (Sweden), now live in Sapporo (Japan). Hold a Ph.D. in computer science and work with computers during the days, perform magic in a bar during the nights (and weekends, for kids). Also used to teach historical fencing back in Sweden.
A guy I know came to the cafeteria wearing a helmet. I am not sure if he is worried about earthquakes (at times books or lamps can fall on you) or if it is a fashion accessory, but it looked bit strange.
