I bet I could guess most of my friends' ages within five years.Do you really think you know how old every woman is simply by looking at her?
I can certainly tell you that the second-year teacher is between 23 and 25. The teacher down the hall who's about to retire and who has grandchildren is absolutely older than me by a good bit. We all know how long everyone's been teaching, so it isn't all that hard to do the math. At church, we all go to Sunday school classes based upon age groups, and everyone in my class tends to have wrinkles of approximately the same calibur.
Age isn't all that hard to estimate.
Now THAT is certainly a generalization.What I meant was that clearly in certain parts of the country people tend to take better care of themselves.
