I was sitting in the NMR room at school the other day, running a neat little test that I didn’t understand (well, one of the grad students was doing the test, but it was my sample) and we started talking with one of the spectroscopists there about whether the presence of the 400, 500 and 600 MHz NMRs in the room actually had any beneficial healt side effects for her, seeing as she’s always there. She said that there was nothing in particular that she could point to, but then there wasn’t anything indicating a negative effect - inconclusive overall. I imagine if THOSE magnets didn’t have an effect, the tiny ones used in those braclets probably didn’t either. ---

By the way, for everyone thinking I’m some sort of vampire, I’m not. Haven’t you ever accidentally cut your finger, and immediately stuck it in your mouth? Or bitten the inside of your cheek? Why should it be surprising that I know that blood tastes salty? ---

> [@](#): > > \*Originally posted by Squink \* > \*\*Ever taste sodium ? Neither have I, but after it gets done burning a hole in your tongue, it’ll taste really bitter, as it reacts with water to form sodium hydroxide, which I can attest tastes bitter, not salty. \*\* As has been explained in the thread, the Na is combined with the Cl, when in solution (such as when NaCl is in our blood) it forms two ions, Na+ and Cl-. Each ion has entirely different properties than each in its elemental form. ---
