Maybe you ought to marry someone who is in your age range.

A study shows that women who marry much older men or much younger men are more likely to die than women who marry men who are around their age. You can speculate about the reasons for that. Assuming the study is accurate, I wonder whether something about a husband who's not your age tends somehow to wear us out or whether women who are in better condition in the first place are drawn to men who are close to their age. I'm going to guess it's the latter — i.e., correlation, not causation. And I confess prejudice: I prefer to be with someone who's my age. I wouldn't want a marriage that had any kind of a parent-and-child feeling to it. It's great to be parents together or to feel like 2 kids sometimes, but who wants to always be the elder or always the junior? People who die more easily, apparently.
