its not the voltage its the current that kills you, but in human terms since you usualy have a very high resistance you need a high voltage to drive the current through you.
which is why its dangerous to have sockets in a bathroom, you will be wet, so your resistance is lower
no one actualy knows the amount of current required to kill you, but its said to be around 8mA. (1000 mA to the Amp)
when some one sits in the electric chair (to be executed) their head is shaved and a damp cloth is put on their head then the skull cap, their ankles are also shaved as this is where the other wire is connected,
now the resistance form skull to ankle is very high but unfortunately(depending on which way you want to look at it) for the condemed person the voltage is not all that high, so as a body has a hgih resistance it heats up as the current flows, so in effect the condemed person is not electocuted, but FRIED to death

fact since its 5 times as much as 8ma.
but it only requires 8mA to actually kill you.
this 8mA has to be across the heart to stop it
it is also why when you see them in movies using the paddle thingy (technical term) they say "clear!" its becuse it has to use such a high voltage to get the current to flow across the heart, any one touching the person when they get zapped is liable to receive a fatal shock, it doesnt bother the person being zapped, since they are already "dead" which is why they are being zapped in the first place
