You are not alone. I call it TheOlderBoard.com as it seems most ladies stop accurately recording their age at age 35ish. In order to assist I've devised an algorithm to accurate estimate a providers age if they fall into this category.
Actual Age = (Posted Age + 5) x 1.1
Example: Cheri (hypothetical name) posts that she's 39 in her listing, but you've noticed it's been that way for years.
Solution: Cheri's actual age is 52.8 years old = (39 + 5) x 1.2
Somewhat joking, but it's probably pretty accurate!
Do you agree?
