<p>It’s a little like choosing a “safety”. You have to ask yourself, if all else fails, how happy would you be as a physical therapist the rest of your life? If, as it would appear, that you are thinking about the medical field generally and are merely looking for a “fall-back position” in case you don’t wind up in medical school, then – and, again I realize that’s a big IF – you should realize 1) you don’t need a sci/med major in order to get into med school, and 2) a liberal arts major is probably a better fall back position in case you change your mind. I mean, why spend four years studying something that will be of no interest or use to you if you should change your mind about being a doctor? Unless, of course, you really want to be a physical therapist. :p</p>
