In my opinion, doing science will, in its consequence, lead the scientist to consider more general questions about science, man and the universe. One of my (now not actively pursued any more) internet projects, meta-biology, is an attempt to start and discuss these questions.
I started out by doing gymnastics (horizontal bar, parallel bars, floor, vault, rings, pommel horse) at the tender age of 5, though. I still practice gymnastics 2-3 times a week. During my four years in Houston, I worked out at the HGC, and in Berlin at the Berliner Turnerschaft. Quite some years ago now I started to go rock climbing every once in a while. In the wintertime I try to go snowboarding as often as possible (since 1990, before then I went skiing). Summertime activities include wakeboarding and kite surfing.
In the evenings, I do enjoy a glass of fine, old single malt whisky and occasionally I go to the movies (science fiction, fantasy, gothic, mystery … you name it).
