^^ Wot he said. ^^
Volts jolts, it's mills that kills.
I think that video could be a bit clearer and more consistent...
"It's wrong to say that the Volts don't kill you".
"Actually you can be exposed to many kV of static electricity and be fine, so the Volts don't seem to hurt."
"8 Amps don't necessarily hurt you either."
"Actually it's the total energy, not the Volts or the Amps."
"Look, here is a table of danger levels depending on Amps."
"Amps are proportional to Volts, so in a way the Volts do kill you."
I could follow along by interpreting "what he must have meant", but if this video does not manage to thoroughly confuse a beginner, I would be surprised. Nice animations though!
