FWIW, as someone in the middle of a medical education, I can tell you that while the vast majority of the stuff in basic science courses isn't particularly applicable, some of the basics are indeed very important. My chemistry and biology courses (to include biochem) allow me to understand why medications that are quaternary amines such as Pyridostigmine don't usually cross the blood-brain barrier, why certain medications exhibit different efficacy in various parts of the body due to pH differences, and why G protein-coupled receptors are both slower and diverse in their actions than ionotropic receptors. Our curriculum is based on the assumption that we already have a fundamental understanding of physics, biology, and chemistry, and thus can understand the principles underlying physiological and pharmacological actions. To put it another way, undergrad put a lot of stuff in my mental toolbox that I'll likely never need, but thus far I've always had the tool for the job given to me in my training. cheers.

See, this is the sort of post that irritates me. It's complete pseudoscience, with a large helping of truthiness. The idea that "natural" vitamins would be superior to artificially-made vitamins *feels* right to most people, so they accept this sort of drivel. See, here's the scoop: form defines function at the molecular level. All that hand-waving about vitamins produced by nature being better is total crap, because a molecule is either vitamin C, or it isn't. Sure, you could conceivably create an analogue that mimics the form of vitamin C, but that would be a spectacularly difficult and expensive task. People, vitamin C created artificially is *precisely* the same molecule as is found in, say, an Orange. Now, if you want to argue that an orange is a superior source because there's some fibre there too, I won't argue that. But these vague assertions about "natural" vitamins smacks of an agenda that fails the critical thinking test.

Likely none, as the body simply excretes the excess. The mega-doses of vitamin C are amusing, as the body doesn't actually retain any of it beyond its immediate needs. Fat-soluble vitamins are more problematic, however, and shouldn't be taken to excess.

Yes, if only they could develop a technology for Hulu that would allow people enough time to get snacks...to pause the action if you will. A button, perhaps. ;)
