Yeah one of my soccer trainers used to help people who had accidents help repair their muscles. She said she enjoyed the work, it sounds boring to me though, all I wanna' do is grow weed.
My mom is one. You have to be able to lift people sometimes, and that can really put a strain on your back. It takes a few years of college, but they also make a decent amount of money. If it's something you feel like you want to do, you should definitely check in on it. My mom likes it a lot, but sometimes they have her do sports medicine, which she absolutely hates, lol.
