I did retirement home training and used to think it was a sweet job. Then I got in the business and underestimated how demoralizing it was as they give you the easy elders in training while the others make you, or at least me, really think of the fact the job just amounts to an unkarmic freebie.
Chiropractors. It's pseudoscience. Maybe it's not the most unique opposition from me as I know some others dislike chiropractors, but I think it's backwards that medical aids or health insurance will literally pay for their client's appointments with these modern day charlatans, while denying payment of scientifically proven treatment options.
