Woah, you had to live in the dark ages of atheism? Congratulations on keeping your sanity.
I wasn't really raised religious, but I was probably around 8 or 9 when I started realizing that Christianity was a load of crap. That led me to my Buddhist phase, until I acknowledged to myself that I didn't know anything about Buddhism. After questioning my previous assumption that everyone has a religion, I began my life as an atheist... except I had never heard the word "atheist" until I was 17.
So if you want to be technical, I was 17 when I declared myself an atheist.

I thing i just got a high score or something.
However long it took to get here, great news is that you finally made it!
I am a closet atheist for 18 years. I am still waiting for that day I can "out" myself.. am in no rush, though. :)
I think I was lucky in that sense, I never really was a xtian. Too much bs.
