It blows my mind too. I worked for a woman some time ago who was a “doctor”. At least that what she said she was, in reality she did foot massages that are supposed to cure everything if done right. When i worked for her i overheard so many phonecalls where she told people to never vaccinate anything and always had a story of a “friend” getting vaccinted and got shingles/alzheimers/cancer whatever and they should get a foot massage instead. As stupid as it sounds, a lot of people took her word for it, because she was a “doctor”
