Answer 1

Your sensation of feeling energetic or lethargic isn’t related to what physicists call “energy.” There’s no reason to expect them to match up. It’s like how if you bought a kit to test for lead paint, you wouldn’t expect it to give positive results for a can of modern paint attached to a “slip lead” style leash.
