Anything having to do with MATH or SCIENCE.
That's pretty much my rule. But hey I'm a hypocrite, I'm going to school for nursing. The only science I like is Biology/Human Anatomy, anything else makes me mental. I'm trying to look past all the math and science and look towards the physical, actual labor. I honestly would not be able to survive in a job where I just sit at a desk all day and do the same things over and over. I want to be on the move, always moving.
