In our old house the cores were wrapped in waxed paper, not rubber,
inside the lead sheath. Joints were made by soldering the wires
together, insulating them with tape, and then wrapping a sheet of lead
around the joint and soldering it to the sheath of the wires entering
the joint. (for example, joints with three wires resulted in a
triangular lead "blob" soldered to the three incoming wires.) Quite a
work of art, but bloody frightening to still see used in this day and
age.

Why's that? Is electricity any more dangerous now than it was then?
