I would say this, but it's not really true! There are parts I like and parts that are... "whatever". I do like watching House and understanding as much as I can and try to figure things out before they happen, but I've never had any medical training, just a strong memory for the bits I've picked up from reading. Also like things relating to mental issues and psych, long before I even knew it was personal!
Hehe, and related to your original post, and remembering those nights on the bench, I signed up for astronomy in college. What a disaster! I was soooo very confused, I had to drop it.

No worries! There are things I can't do at all, and confuse the heck out of me. See astronomy above. Also, accounting, physics, things with motors, and calculus (which I couldn't even remember the name of just now and had to look it up!) among many others.
