Sorry I didn't mean to call you a liar, I'm just trying to understand how the laws of physics somehow don't seem to apply, I wasn't being facetious. It just looks to me if some sort of mis calculation is going on. It takes a certain amount of energy to move a known weight a certain distance, that's what Im getting at. For example it would be possible to calulate how much energy, ie calories, it takes to transport a certain weight over a certain distance in a certain time, that is an inescapable law of physics, why then, can your body seem to do it with less energy? The short answer is, it can't so there must be some miscalculation somewhere. That's what I meant, I'm not calling you a liar, I am quesioning the accuracy of some of the factors. You may sincerely believe them youself but something somewhere is innaccurate. It's not a personal attack really, it's quest for understanding.
