I've been meaning to say this for a long time. I often enjoy the debates of Sheila & VeeEnn.....Thing is, Charlie, the back and forth that goes on with threads such as this one aren't really "debates".....as in a free and equal exchange of ideas etc. (or whatever debates are supposed to be) and the *recs* that're generated either way aren't worth that much in the context of any sort of validation of knowledge, skill or expertise.See....biochemistry, metabolism, physiology etc. are sciences for a really good reason and you really have to know about them to know what is and what isn't and what you think you know (or believe) that *just ain't so*. For sure, I'm not at the top of the game with any one of them (as OleDoc could surely attest) but actually having to study this sort of stuff in a didactic setting, accompanied by lecturers and test examiners letting you know just how bad U GOTZ IT RONG!!1! tends to generate a bit of introspection when it comes to bloviating freely about stuff like this.
