I am a mathematics enthusiast, although I have no formal training. What I know is what I've been able to glean from searching Wikipedia.
I enjoy writing computer programs, although I have never been employed as a programmer. I've used two-dozen different programming languages, but my current favourite is Haskell.
I also have an interest in various areas of science.
On top of all that, I'm also a bad musician, a mediocre dancer, and a very bad juggler. :-P
