Watching a whole cluster of friends, and my own mother, die over quite a short space of time convinced me that purely materialist 'explanations' for our mysterious human existence simply won't do - on an intellectual level.
My brain is a big cluster of stuff. It moves quickly and loses focus quickly, so I need many projects to keep me stimulated - it's a luxury to be able to do lots of different things: style, write, present, DJ or just consult.
