At 71 I am "salt and peppa", too. 15 years ago I asked my hairdresser about coloring it and she said I'd have to find someone else to do because SHE was envious of my "silver" gray and wouldn't want me to change a thing, hahaha!! That was all the "permission" I needed to forego the time and expense of worrying with it, and I'm so glad I didn't start that!!
For me, skin is the great pretender. I've been blessed with oily skin until the last 2-3 years of my life and have only some age-related droopiness (which I just despise!) but few if any wrinkles. I pass for 10-12 years younger all the time.
