One piece of advice to women entering college should be.... Don't wait very long to get married and have kids! Duh! Not only does the pool of eligibles drop as you hit your thirties, so does fecundity.
People like Cathy Young may rationalize it away, but most women idealize marriage and family (look at all those Bride magazines out there). She may say she's content, but I would think that's a minority position for someone in her circumstances. What a lonely way to end your life, with the only pictures on your mantle being that of your cat! Yecch.
It's a long, lonely time to reflect.
