 Now a quick overview for the lingo, if you're not familiar, resident is basically somebody who's finished medical school and is going through their three or seven year training to be that kind of doctor. So I spent three years to do internal medicine residency and now I'm doing sub-specialty even further to just be a cardiologist, so three year fellowship. But usually between your residency and your fellowship you get board certified in your broad field. So I got board certified in internal medicine. I can work as an independent medicine doctor which I actually have done as a year as a hospitalist. If you guys are interested, I'll go ahead and link that video up here or as well in the description. But as you can imagine, because a fellow has more certifications they have more opportunities to work both independently as well as oversee other trainees. So when I was a resident working in the ICU's often sometimes there wouldn't always be a supervising attending in-house in case we had an emergency but there would be a moonlighting fellow that'd be usually in cardiology, a pulmonary who had their medicine license. It could just oversee us making decisions. So we had no indication to bother them because we kind of knew what we were doing overnight. The fellow made a decent amount of cash which we'll go to in a second and really not do anything.
