I didn't spend a lot of time out doors as a kid (as evidenced by my skin tone and weight) but spent a lot of time on computers. I remember everything from the 8088 to the 486, the first Pentiums and roughly up to the gigahertz days. By then I was too busy with other things to spend much time fiddling with computers, I just want them to work now.
When I wasn't on the computer, I was usually reading or playing RPG's with my friends. Yes, that's role-playing games. That includes Dungeons & Dragons. I've grown out of that now, but as nerdy as RPG's might be, I consider having played them a positive. My interest in making up realistic people/characters led to learning more about the world (as it was and is now). It also acted as a nice focus for my interest in psychology and what makes people tick.
If you prefer labels, I'm a bit of a geek, a bit of a nerd (there's a difference), a gamer, and an IT professional. I'd also like to think I'm a comedian and philosopher, but I usually only give myself those labels when I'm feeling particularly awesome (and likely need my ego-bubble burst).
