Either way I've noticed this - volatage seems to be measured accuractly near the tip of the lead, readings on resistance are depressed - in order to accuratly get the Ohms, I have to press it against the part of the lead above the burning. (I think I did that many years ago - my dad tried to show me how to do something with the iron and, well, the rest is history.)
I won't have time to see if that goes with my pulse tonight. While it easily could be some kind of a chemical reaction, that'd just be rad if it was the byproduct of something not fully understood (although, someone, somewhere, probably knows). On second thought, I think I saw on a T.V. show a some time back that said how well you survive lightning has something to do with the momentary state of your electrical 'cycle' at the instant of getting hit - and that people who have survived such encounters claim to acquire strange electromagnetic properties (such as cuasing stoplights to behave erratically whenever they apporach.)
Alas, I'm not sure how to test this against pulse, I could look at the rate for example, but only if somebody helped me count to find it.
Again, thanks for the interest!
