Isn't it funny how soooo many posters here look 15-20 years younger? (Or have a sister/friend/mother/aunt/granny/neighbour etc who does.)
Don't ever see any 'I get mistaken for 15 years older' threads/posts though. Funny that. 
Also, what's with all the comments like 'I was over the moon when someone asked me for I.D. to by booze because I am 38!'
And many MANY more comments from posters absolutely THRILLED that someone (allegedly) thought they were younger than their age.
Why do so many people need this validation? Why are people so insecure that they NEED people to tell them they look younger? 
Also, why do people even tell you this? And what happens??? Do you say 'hi I'm Sam/Louise/Sharon etc, I am 39,'' and the person you offer this information to says 'oooh you don't look it.' 
And if you are asking someone to GUESS your age (which I am guessing some people on here do,) just remember that most people will knock 7 to 10 years off to be polite.
One woman asked me to guess her age some 3 years ago, and I thought she looked 57-58, so I said 'umm 50-52.' She was 51, and absolutely disgusted that I said 50-52. She said 'well most people tell me I look 42 to 43.'
The silly mare was insulted because I guessed her age RIGHT! I imagine she is probably a mumsnetter actually. 
And no I am not 'jealous' or 'bitter' as someone laughingly said further back, why the F would I be jealous of someone who is deluded enough to think they look young enough to be their own child's sibling?
Everyone looks their age - within 5 to 8 years. Yes, even most black people/POC. Their skin looks quite good, and some of them age well, but they don't look MASSIVELY younger.
Anyone who is mistaking you for 15 years younger either a) needs glasses, b) is shit at guessing ages, or c) is taking the piss. Because you DO look your age, (as I said, within 5 to 8 years.) Some people look GASP actually OLDER than they are. Even some of YOU
