I'm 25 and I'm now starting to look at young lads in the pub as 'kids' and wondering to myself if they're old enough to drink. Thats a true sign that I'm getting old. :/ I think you'll find that most 'kids' don't feel that at home here, as it's generally very laid back and mature. I could be wrong. There's a lot of guys in 20's and 30's on this particular site I think. But good for you starting young, I starting teaching myself web/graphic design from 13 and it certainly did me no harm.
