Welcome to the dark (grey) side. I could complain about going grey - I have more white now on my head and beard than any other color - but then I would have my two BILs and maybe a regular or two in this thread telling me I'm lucky I have all my hair. We can't all be like our resident 007. My FIL has a rim of hair with a few strands combed over and both my BILs chose to start shaving their domes around 30.Unlocked a new level of the game of aging.
Plucked a completely white eyebrow hair out today. Took another 12 hairs or so along with it, but was finally able to remove it.
That's just life experience and wisdom physically manifesting. Wear it proudly, girl - or color it as you see fit. Either way you've earned the right.
