Default C4 Racing from Newbury - 2 horses *electrocuted*

Nearly all animals need far fewer "mills that kills" (current)
through them to electrcute them than humans do. I don't know if
it is known why humans are more resistant to electrocution than
most other species, but I don't think the 6 or so generations
since the widespread use of electricity is long enough for
darwinism to be a factor, unless there had been an electrocution
pandemic, whereas it's actually very rare.


Anyone electrocuted before they breed is weeded out of the gene
pool, but I agree that would make only a marginal difference.

BTW, the word 'electrocution' is short for electric execution but
these are accidental deaths; however, I guess that's preferable
to the media using it to mean any (survivable) electric shock.

And 'pandemic' just means a disease unconfined to one location, it
doesn't mean the disease is deadly or that large numbers have been
infected; another word which is wilfully misused by the media.


Most humans will have experienced an electric shock, know what
it is, and know what to do to stop it. None of that is true of
most animals, and as I said before, when an animal is being
electrocuted by the ground, it can't "let go".


Hmm, perhaps we should shock toddlers, to train them...


When you have current leaking through the ground, it causes a
voltage difference across the ground. Let's say we're standing
on a piece of ground which has a voltage difference of 10V/foot.
Your feet are probably about a foot apart, and even with bare feet,
you wouldn't even feel 10V. Even if you did, the current path (up
one leg and down the other) isn't going to kill you. A horses feet
might be 6' apart, so it's going to have 60V across it. Futhermore,
that will be across the chest (heart, lungs) and much more
debilitating. Metal shoes will make better ground contact, pressing
right into the damp soil, although it's a very serious problem for
unshoed livestock too.


In that case, what voltage *would* it take to kill a human, when the
current passes through each leg and not across the chest?
