I really expected you to say that they were "polishing a turd"! [1] On the flip side, you have to admire people who are becoming actively involved in their health AND learning more about the basic functions of human anatomy. A long time ago, it was illegal to dissect cadavers and medical knowledge required committing a crime. Isn't it better for smart people (who in theory understand the risks) to be allowed to conduct even uncontrolled experiments?
