Which isn't such a big deal, until you realise in five years time you'll be ticking the over thirty box, and that's just way too far ahead for you to think about right now. Ticking the second box is also a slap in the face, forcing you realise just how long it's been since you turned 18, and how many people there are younger than you in the world right now. You were proud to be Generation Y; but now Generation Z is taking over with their youthful good looks and their racing metabolisms and their parental handouts. YOU'RE OLD NOW. And the box ticking proves it.
