Get ahead, crime scene examiner or a general surgeon...?

Some hospitals might have a "medical explorer" program for high school students or a volunteer position with patient assistance for you to spend time in a hospital and see how you like it. You could also contact a local doctor's office and ask if you could shadow for a few days (or afternoons) to get an idea of how a medical career looks. Some states have an Area Health Education Center (AHEC) that helps coordinate experiences like this. Visit http://www.nationalahec.org/home/index.asp for more info.

Sugeon is probably better if you can do it.

Crime scene examination is often tedious and boring.

Personally, I found the most excitement and made the most money as a crime scene creator!
