Tough to judge a woman’s appearance by a police booking photo. She’s probably seen better days. But to put a little different spin on this, the Kinsey types say that the male reaches his peak sex drive at age 18 and a woman reaches hers at 35. So, is it not tempting nature to put a 34-year-old woman in a classroom with a bunch of sexed-up juniors and seniors without having some women (particularly if childless and feeling the tug of their reproduction clocks ticking) give into the temptation, particularly as they begin to feel less attractive and desirable?
Yes, sense should be telling her not to go there but tossing a woman of that age into a high school classroom is a little like tossing gays into an all-male prison.
Historically, at 18, a guy has no certainty he will live to an old age, so he might as well impregnate as many women as he can. Girls, on the other hand, have an incentive to be choosy during their years of peak sexual attractiveness. At 35, with the end of her reproductive life approaching, a woman's body tells her "the time for being choosy is over, reproduce while you still can". Or alternately, "it's best to keep your mate interested with frequent sex, so he doesn't go off looking for a younger, hotter woman".
