Possibly, although it seems unlikely seeing as my mother just turned fifty and she still looks about 35. If she hadn't had three children two of them very large boys, I think she'd probably still be as lithe as I am currently.
No, people are almost never accurate when trying to guess my age. I'm 22, but most people think I'm about 14-16 irl. When I get carded at bars, the bouncers usually stare at my identification for five minutes and run it through every available scanner and usually stare at me for long periods...
