The message
from "David Hill" contains these
words:

The message is clear.....
If you live in an area where you are likely to have a visit from an intruder
who has a heart condition and a pacemaker and who crawls around on his/her
hands and knees then forget the electric fence.
With a fence height of 9 to 12 inches you wont even feel a thing if you are
wearing trousers, jeans etc.

And unless your heart is in your boots........
