I reckon it's all in your head. I just hit 24 last week and I don't feel a day over 12 in my mind

Still watch cartoons, play video games, hang out with friends and do stupid things for the sheer pleasure of it (nothing destructive of course

). Despite my physical age, nothing can change my age at heart. Did it then, doing it now and probably will still be doing it when I'm withered and old.

(maybe not the backflips but you get the idea

)
