...just discovered this post. Anyway, my $0.02 on the subject... I worked in a hospital medical laboratory and in EMS for a number of years in my early twenties. One thing I noticed during that time was that PT and OT (occupational therapy) people ALWAYS seemed like they really, truly enjoyed their jobs. Of all the medical personnel I've encountered in my days (including physicians), PT and OT have always been some of the happiest and most content people I've ever known. If there was any way I could hit rewind on my life (knowing what I know now), I would jump at the chance to go to PT or OT school.
