Static electric shocks regularly run into the kilovolt range. So why 
don't they kill people? I assure you, if you hang somebody between a 
pair of 40 kilovolt overhead power lines, their body will be reduced to 
ash - possibly explosively.

The difference is that a static shock lasts for an infintesimal fraction 
of a second. That's how long it takes the two charges to neutralise each 
other. If you touch a power line, however, there's a giant generator 
replacing the charge as fast as you can neutralise it, causing a 
_continuous_ current flow.

It's current that kills you, not potential difference or anything else.
