I'm 23 and really don't give a crap about how old i am. If i enjoy something (video games for example) and it makes me happy then i'm not worried. The people that make games are old and they love it still.

I will probably be playing games when i'm 50 ok maybe 35 but when i have kids i'm sure i will be playing with them.

Don't get yourself down because your in your 20's
