When touching an electric wire, why do you become electrocuted when touching the ground, but not when you hang in it (or stand on it like a bird)?

Answer 1

Electricity has one goal – to reach the ground. When you are in contact with the wire and the ground you present a bridge for the electricity to reach its goal so it passes through you, fucking you up a bit on the way.

A bird doesn’t present a path to do the ground so electricity doesn’t give a fuck
