I got the "forever young" genes in my family.
Still getting more than the occasional blonde facial hair (peach fuzz) at 29 years old. Even though I've had both grey and silver hairs popping up behind my ears. (mostly due to extreme stress)
My hair is lighter than it used to be, a combination of lots of time in the sun and just a wee bit of graying that will obviously continue.
My beard is another story. My beard, as I have matured, isn't getting greyer. It's coming in redder.
I'm not complaining, and it's a fairly common phenomena.
It's still weird.
Genetics is a rad field of study.
