@MariaTheMartian Ooh! Thank you for sharing. I'll read up on it. Interesting. I'm in my early 40s too and mistaken for late 20s.
If I cut my hair, like army cut, people start to mistake me to be in my early 20s or late teens. 😅 It's why I'm keeping my hair long, because the public treats late teens and early 20s differently for some reason. (I'm fine with late 20s, haha.)
