Going by when I got into the fandom, I 'should' be eighteen or nineteen by now (omg wtf fandom turns five this year)... but yeah XD
Non-squeefans tend to skew older / more mature, though >.> I've just noticed that. (Also omg dude have you ever looked at your hands? Like, really looked at them?)
No, it's enjoyable -- I made a munchie run for pie earlier because I really wanted pie, dammit, and I've been giggling at everything all night -- but right now I've hit the bit where my jaw hurts and I just want to sleep.
