Heh, I always used to not give it a second thought when I heard about people talking about events of their past, like JFK and the Cuban Missile Crisis, but now it seems strange to me that there is a generation of people who were born after the wall came down, or after 9/11.
It's a stupid thing to say, I know, but it's just one of those things.
Anyway, congrats and Happy Birthday! Funnily enough I was seventeen when I first joined up here, I'm 27 now. Trust me, getting old will come when you're not expecting it.
If you want a preview of it, try and keep up with computer technology.
