I'm incredibly interested, but seriously, I have a difficult blue collar job, and at 47, I'm not going to go out and get my Master's in Chemistry. It's not that I'm dense, I just don't have the time. So I picked "Moderately interested in health science" only because I'm not "familar with the hard science"... yet.
I try to immerse myself and understand as much as possible. And every day it seems I catch a little more.
