I would look into Kinesiology as a major if you're interested in PT! It's all about movement and the physical body. I would also suggest volunteering to shadow a PT as well, to get some experience and make sure it's the job for you :). Google physical therapy and the city you live in, call, and tell them a little about you and ask if they take volunteers or if you can volunteer/shadow. They can give you a lot of information as well :).
