I like sim racing.
If you like on-line racing with real people try LFS if you didnt allready. Its better than any other sim, awesome physics. I like Richard Burns Rally also but LFS is another thing especially at on-line.

I like music also, I play guitar, make home made recordings & songs.
Investigating on ancient civilizations also another interest of mine.
