Single pilot IFR near minimums is scarier than BASE jumping, I've done both, it's very dangerous in piston singles, large commercial is orders of magnitudes safer with turbines, modern electronics, and two pilots sharing the workload...
I bet there are a bunch of us... I'm not sure knowing more jumpers going in than pilots is quite valid, jumpers, especially BASE, tend to be more "cowboy" than the average IFR pilot, jump at bridge day and meet your peers.. ;-)
I have family that are MD's and it's very common (or was) for doctors to get their pilot's license. I was told about death pools are common for new pilots, with surgeons being seen as the more likely to die due to their less risk adverse nature.
Sorry, my phrasing is a bit funny :) A surgeon is considered more likely to take risks in treatment vs a general practitioner. A surgeon is also more likely to die in a small plane crash.
