You can actually put yourself in a metal cage and put a half million volts through yourself and not feel a thing as long as your body is at same potential,and not grounded. It's Amps that k-ll. Only takes .5 amps to k-ll you. As far as heat, we are much better furnishes then conductors.
our bodies are INSANE at creating heat. fun fact of the day: our bodies produce so much heat, and the acids in our stomach are so terrible that our bodies actually hav something inside them that stops those acids from starting our body on fire.
