 And welcome back, George Norrie with Mark Hartsman. Mark, who is Dr. Hercules Sanchez and what did he do? So Hercules, he had this amazing quack device in the early 1900s called the OxyDonor. And so medical quackery is another thing I'm fascinated by. It's just these different kinds of gadgets and devices that supposedly would heal everything, right, and make everyone better and people would pay lots of money for these things.
