Somehow the subject of running comes up, and Bill doesn't believe in running for exercise, apparently. He says God made us too smart to run, which is why we can use weapons to hunt, etc, etc. I busted a fat ACTUALLY on him and set him straight that running is the reason we're the dominant species on the planet.
We're bipedal because it conserves energy as compared to running on four legs. I explained that the animals could outrun us at short distances, but thanks to our running on two legs, we could run for longer, giving us a very high success rate in killing prey.
He acted like he understood but said something along the lines of "that must be how we killed all the dinosaurs," so I'm not sure if he fully grasped the concept.
