Actually many people do die from blows. How bout you volunteer to take one shot to the body from the current world heavy weight and claim energy doesn't kill, and treat kinetic energy like an unproven theory. You could also throw your body from a tall building comfterble in the fact that after striking the ground that you'll live the 1-2 minutes a human takes to bleed out from massive internal hemroging, or just die instantly like the rest of the people who have had the misfortune (on purpose or otherwise,) of finding this out. We could relive the awful capital punishment of burning people at the stack were energy burns and cauterizes your wounds so no bleeding occurs yet still you end up deader then a door nail. Or better yet you would do us all a favor if you licked your fingers and stick them up a live light bulb socket. It will be magic in your world how you die with no blood loss from this one. Stop arguing with straw man tactics, it's annoying.
