I'm 24. I got my first laser in summer of 95, a Calpac Lasers keychain out of "The Edge Company" catalog. I got my first green laser from Deharpporte Trading Company in 98 (long before they went private). So, since my birthday is in November, that means I got my first laser when I was 11, so I've been using lasers for 13 years.
Damn, I've never actually thought about that before.
