i am a high school student who wants to go into the medical field, but i don't know which health profession to pick. Since i want something where you actually deal with blood, think, interact with your patients, and is interesting. In other words i do not want to seat on a chair and just prescribe medicines to my patients. Plus i also want a career where you just don't work with one sickness, but with many. I know that will probally mean physician, but i want to be able to also see the body system of the patient. Whether it is blood, organs,etc.
