... all the famous pop stars and actors are now younger than you.
... you feel nauseous at the sight of food colouring.
... you feel scared or annoyed around rowdy teenagers.
... people start asking their kids to call you "auntie". You kick up a fuss and they say "oh ok jie jie then" but look at you disgusted.
... you can't get to sleep much past 11am anymore on weekends because you're too used to waking up early for classes.
... you start preferring vegetables to fried chicken.
... you're too tired to do anything on Friday night except watch a DVD or read to sleep.
... you stop wearing earrings besides the ones at the bottom of your lobes.
... you don't know 70% of the bands on hitz.fm now.
... you marvel at the energy and enthusiasm your juniors have for Friday night.
... you realize you've stopped worrying about whether you look cool for some time now.
... you start planning how much Botox you're gonna have. HAHAHA.
... you don't mind eating alone.
