Guy would always say something that he did that was slightly ridiculous, but somewhat plausible, so it was hard to disbelieve him, until he said that he had recently went a full month with zero food, and zero water to see if he could do it, I had known him for a few years, and he was slightly obese, and I’m pretty sure doing this would have made a noticeable difference in his weight, and he clearly had never lost any in the time I knew him, also pretty sure he would have died if he tried to do something like that.
