That's really interesting. I've never used one of those sites before, so I was just playing around with it. Pics taken of me in 2012 say 36m, last Feb 29m, last Sep 35m. It says my gf is several years older than she is and she's a total baby-face.
Last week I had been playing with my hair in the bathroom mirror and decided to take some pics because...well, just because. And I was actually slightly happy with the pics! Probably the first ever of my life I haven't -completely- hated, only mostly.
But anyways, it said female for every one of those pics, age anywhere from 24 to 31. It's got to be a combination of the hair and the fact my phone takes awful pictures (and I can't hold the camera steady), but I'll admit to being pretty happy about those results :p
I guess I can't really come in here claiming that without sharing the pic, so...here's the one it says is 31f. Sorry for quality, dirty mirror, etc. I wasn't expecting these pics to turn out worth a crap, really wish I had cleaned the mirror! Also, this is my first pic making it to Susan's...so...whee!
