Mostly useless trivia

Did you know....

1) You can actually kill yourself with a simple 9 volt battery? I was in class today, learning how to calculate currents that might go through the heart. The prof made some mention of a Darwin award and a 9 volt battery. See, while the skin has a relatively high impedance, your blood and the rest of your organs do not. This guy (about halfway down, starts with "A US Navy safety...") shoved the leads through the skin, which provided enough current to stop his heart. (just as a note, most 120V outlets in contact w/ skin at a short duration isn't enough to stop your heart, although i still wouldn't recommend trying it...if you really want the proof, just ask me).

2) Smoking accounts for 1/3 of all cancer deaths. AND, smoking also accounts for 1/4 of all heart disease. Cancer and CV events make up #1 and #2 causes of death in the US. They've traced smoking to oral, lung, stomach, renal, bladder (etc etc.) cancers. The moral....QUIT SMOKING
