Taking care of someone who’s really sick surprised me, because depending upon what your fundamental nature is — and this isn’t good or bad or better, it’s just the way you are — is that for me, the sicker the patient, the better I function. That’s why I went into infectious diseases ultimately, because it’s such a dramatic aspect of medicine. You die or you get better, that kind of thing. But I loved every aspect of medicine. Probably the most enjoyable part of my medical school was — something I didn’t do ultimately‚ was OBGYN, was just delivering babies. I mean, the phenomenon of delivering babies was amazing.
