Ol’ King Fred was quite the budding scientist. Then there was the time he got interested in digestion. Frederick wondered whether digestion was faster when you rested after eating or if you exercised. He had two men brought from his prison, fed identical and sumptuous dinners, and sent one off to nap afterward, while the other went for a strenuous hunt. That phase of the experiment completed, he had both men returned to his court, disemboweled in front of him, and their innards examined. The sleeper had digested his food better.
