HI
In the early days of the electric chair, Edison called
AC the killer, because the AC nature effects the
heart.  The Nazi's killed with both and found that
women died easier than men, and AC 50 Hz was a factor
of at least 3 lower current to cause death.
LD 50 for women was 40 milliamps I believe.  

Lightening does what it wants.  I lost two friends
from lightening, neither was struck, but only standing
near where the strike occurred.  Both were knocked
unconous, and died due to asphixiation.

I got hold of 120 AC once and passed out unable to
reliese my grip.  I only survived by collasping, and
falling to the ground forcing my release. I also got
bit from about 500 volts DC on a solar array hurt
like, but I only touched did not grab.  Don't try
this.   
Thanks Daryl
