To your body.

No :) There must be a difference in electrical potential for current to flow between two points.

If the body is insulated from ground, the body is at the same potential. No current flows. No material conducts anything :)

For the same reasons, high voltage repairs can be done live from a helicopter: https://m.youtube.com/watch?v=9YmFHAFYwmY

Around 1:10 you can see the lineman connect the mains to the helicopter, to neutralize any potential difference.

After that, the lineman and the helicopter are at the same potential as the cable, so no current flows.

If someone dropped a line from the heli to the ground however.. zap!
