The amount of times I've heard "you don't look early 30s", and no, it's not a 'boast' before some posters become enraged that someone's been told they look younger than their age and they haven't.
It just makes me wonder what people are thinking, is there really a dramatic shift between 20s and 30s? Maybe a couple more lines, but you can get those lines in your 20s too.
It just baffles me, it's either social niceties or people just opening their mouth without thinking.
Honestly think some people are stuck several decades back where 30 year olds got perms and elasticated waistbands.
