I agree that married attendings and/or residents would bring an interesting perspective to this debate. That said, experience =/= the ability to read sociology journals and glean accepted, 50 year old, Chicago School truths. For years, researchers have proven that married couples who share similar interests and a similar line of work are significantly happier and drama-free than others. This is certainly not to say that a doctor couldn't be happy married to a schoolteacher, a pharmacist, or a mechanic; just that, in the long run, couples in the same line of work will likely see the world the same way and will thus have more in common. (Research has demonstrated that profession can sometimes be more powerful a factor in determining relationship outcomes than both income and religion.)
In my view, the most important criterion for my potential hubby is a pronounced forebrain.
