Funny thread. I don't know why people assume that if someone is attractive/hot, etc, then that person is superficial, dumb, etc. You can have both. It's not as easy to find if you're picky, but you don't have to have an unattractive mate/wife to get some loyalty. Plus unless you're really not that sexual yourself, I don't see such a relationship lasting. Once you do meet the right person (attractive, intelligent, etc) your marriage might fall apart. So I don't agree that one should consciously sacrifice physical attraction to satisfy personality needs. That's just a self-deception. It's another thing if you truly care about someone and don't even notice how they look. But making such a choice consciously is bound to create unhappiness in the future. And there is a clear difference between an attractive "bimbo" (which I think is what most people are referring to here) and an attractive, but well-rounded person. Think Paris Hilton vs Jennifer Connelly.
There is another explanation why doctors as a group might not be able to find the most compatible mate. That generally concerns social ineptitude. In order to find that one person who is attractive and intelligent, you need to be able to get to know many different people and filter through them. This implies the ability to approach someone you find attractive. Most of us in the hardcore sciences have a social handicap. This is especially true for doctors since they also have lack of free time. Without much practice, you probably won't be able to attract/retain the right person once he or she does come along. I equate this to preparing for the standardized tests, like the STEPs. If you don't practice a lot, when the STEPs come along, you either fail or perform poorly. Personally, I think many doctors end up marrying Asians because Asians have a certain quality of being down-to-earth and are much more approachable than many of the girls made in USA. Just an observation.
On a side note, from what I have seen, WS, you seem to be pretty attractive. I have no idea why you're still single. And I know you're joking, but I know a girl who was so disappointed by male partners that she started dating girls, on and off. I think the sexual boundaries for females are far more blurrier than for males. Freud mentioned this decades ago, but I think some females still don't agree with his analysis. A large percentage of sexual dissatisfaction among females probably also has to do with this statistic.
