Even been told you look either older or younger than you really are?  Were they being extra nice or a bit nasty?
Well how about letting a computer have a look and give you an answer based on an equation?

Microsoft’s website how-old.net can do just that with users uploading a photo of themselves to then be delivered a determination of their age.   For me it was quite close with the computer’s guess coming in just a year younger than my actual age…but for some it has given let’s say, somewhat discouraging results.

Try is for yourself at  how-old.net.
