trouts59 - My ela was born on Feb 29, they do not age slower

Voidhearth - nope

bookworm100043 - technically doesn't the year start/end for you on your birthday?So no, but technically yes...

lightning_999 - Um... In age technicalities, yes they do age slower. But they look the same as like, their friend who was born the same year.

ChasingShadowz - There's a Teacher Assistant at my school who's birthday is on Feb 29

Fitzphie4thewin - I have a friend who's technically three...

lulu_officially -  In a way, yes, if age signifies who you are. But what really counts is how long you have been on this planet. So technically... No. Unless you count by age. But I don't.
