Full time intensivists are the wave of the future. For me, I plan on doing pulm/cc for a few key reasons:
1)I would probably kill myself sitting in the OR for hours on end with little to do what with my ADD and all. (Quick story: Coolest surgery I've ever seen was a repair of a total anomalous pulmonary venous return at Joe DiMaggio Childrens Hosp here in FL... 12 people in the room, video monitors so everyone could see, full bypass, etc. The anesthesiologist? Sitting in the corner playing solitare on his Treo.)
2)All kidding aside, most importantly, I want to be an intensivist, so IM would clearly prepare me better (though I do like SICU/trauma patients.. they're so young and heal so well!)
3)Once I'm old and decrepit, having made sufficient money working myself half to death for 30+ years, I can open up a sleep lab, work a couple of hours a day telling a bunch of obese people they have OSA, and then hit the golf course!
(Although, reading the FAQ, doing ID then CCM might be interesting too; certainly easier to get the original fellowship, I would think)
