If 66, I really doubt you look 46. But good try....
An important part is that I have a full head of hair and almost zero gray. My mother is 92 and, like president Reagan, has black hair with the occasional gray strand.
i.e. it’s really just genetic. However, think of me as a car that was always garaged, but has 400,000 miles on it. i.e. I feel older than 46. :)
Good explanation. Im 56 and have aged well, except for the Texas sun! Never tan anymore, its cooking your body not tanning it!
