A few years ago, I briefly considered going back to school, getting a degree in Exercise & Sports Science, and getting into athletic training. But in the end, I could never quite convince myself to do it, and the moment passed. I also flirted with the idea of becoming a private detective a couple of times in my life. I actually still find that idea somewhat interesting, but I doubt I'd ever make the money doing that,…
Private investigators with a good grasp of IT are very rare and white collar crimes, etc are rife. As for the training, much of it is common sense and not above the levels required to get a degree in any other field.
