When I was working, I used to dye my hair. I thought it was an advantage to look youngish at work. But as soon as I retired, I stopped dyeing my hair. It went completely grey, almost white, It took me a while to get used to it, and my family and friends even longer. It's hard for women, so thoroughly trained to keep looking youthful, and many can't bear to give that up. But if I can't free myself from all that brainwashing when I'm a senior, then when am I going to do it? Bonus: I get offered seats on the subway more often. Should I take the seat, just to reward people for doing a good deed? If I'm feeling spry, I usually tell them I'm okay to stand, but I make sure to thank them for the offer.
