How do you determine a woman's age?

My neighbor, an 88 year old man, had to go into an assisted living facility two months ago.

To pay for that, his family had to sell his house.

The woman who purchased his house, when I walked next door to introduce myself, looked to me to be about 35 to 40 years old.

The son, of my neighbor, who had to sell the house thought the young woman who bought the house appeared to be middle aged. I am 50, so I figured this woman would be around my same age. When I met her, last week, she appeared to be about 35 to 40 years of age.

My Dad, aged 87, went over to drop off the mail box key today, and reported back to my mother and I that the new homeowner was in her early 20’s.

I’ve met the woman twice, and both times, I would guess that she is in the 35 to 40 category.

My mom has not yet met her, so she has no opinion, other than to be dismayed by the possibility that this woman is either in her 20’s or her 60’s. A huge discrepancy.

I am 50 and have been carded for attempting to purchase decongestant for my allergies, and rum for my Xmas rum cakes, as well as for the occasional lottery ticket. They have a sign at the cash registers (at least they do in CA, that they will ask you for your age if you appear to be under 30). In CA, you have to be 21 to buy alcohol and 18 to buy a lottery ticket or decongestant. I’m 50, but get carded all the time.

Do any of you think that you could not tell the difference between a 20 year old woman and a 50 year old woman, or a 60 year old woman?
