-----
The only medicine I practice is the kiss & a band aid type & I got my license to practice that kind of medicine after pushing a baby out of my uterus. No fraud there.

Other than that, I don’t think I pretend to have knowledge in any field, except maybe parenting. I think all parents are frauds. How could you NOT be a quack when you're pretending you know how to do something that you've never done before or been trained on!

I have bits and bits of knowledge in all kinds of areas, but I try not to claim to be skilled in any of them!
