Takes more than a patented attitude adjustment to carry off this circuis trick. Usually it’s part well calloused feet, and part coals that have burned down to the point that they are well covered with insulating ash.
There, it's fixed.
I get the impression that they hired up a new crew to do the burning coal trick, and the boys actually thought they knew what they were doing.
If you are in need of that much confidence...you’ve got bigger issues, and ought to start with painting your garage in 95-degree heat, or digging up a septic tank.
