I just started physical therapy school because I was done with full-time desk work (and other reasons). The job market is pretty good and it pays more than enough to get by. Of course, like @Magic Poriferan points out, most jobs use computers to some degree, high- or low-paying. But computer time is much lower for physical therapists than for the typical desk worker.
Anyway if you are interested in PT, the profession is moving toward doctor of physical therapy instead of a masters, so at a minimum that would be a 4-yr bachelors and then 3 years of the doctoral degree. Here's some info on the career and job market: http://money.usnews.com/careers/best...ical-therapist
Feel free to ask me more questions if you are interested or want to know more!
Your kisses, sweeter than honey. But guess what, so is my money.
