Yeah, well, Jeri. I used to teach this stuff. Admittedly, as a graduate in plant science, I had to look a lot of stuff up when it came to animal anatomy and physiology. Many moons ago, again admittedly. And, I must say, that, unlike Maggie, you at least put Donuel and me on the same footing. Progress of a sort, I suppose. I'll rein meself in, but it behoves all of us to call out Donuel-style misinformation when it's peddled on this site, especially if it's couched in terms of "medical advice."   In m'humble, as ever.
