Although we'd all like to think we're unbreakable like The Rock, the truth is most of us are merely mortal—and we can get hurt. Sports, adventure, and sometimes just walking through life can get us things like pulled muscles, broken bones, pinched nerves, and far more serious injuries. Thankfully, physical therapists (PTs) are around to put us back together. These are trained medical pros who can diagnose physical ailments, create plans for recovery, and use a variety of machines and techniques to guide patients through rehabilitation. PTs can work for hospitals and clinics, or they can be their own boss, visiting patients at home. It's a great, growing career for active people looking to help others, but be aware that a Bachelor's and Doctorate degree are required in this field.
