Ever wonder why kids look so silly when they run? It's because they have dishonored their family. Got you! It's actually because they have no kneecaps until they are 7 months old, and then when the kneecaps finally come in they aren't strong enough to hold their weight. Got you again! You didn't actually believe that did you? Man, I'm on a roll. It's actually because they have short legs, which means they have a shorter stride, so there isn't enough time for their little legs to come off the ground long enough for them to look normal while running. Usherwood says, "Even when they think they're running, they're barely getting off the ground." So it's not that they are bad runners, it's just that they physically can't be good runners until they grow up. Our legs are way longer than a child's, they could probably kick a football like two inches. I've been doing intense all day leg workouts that could kill six dragons if they tried, so I know I could kick a football at least 450 centimeters. I'm not even an adult yet so take that kid. Get on my level, bub. My legs are longer, which means my stride is going to be larger than a child's. My legs will be in the air longer than theirs, so I'll be able to run and look normal, while they struggle and run as best as they can. So if it were a survival-of-the-best-runner type situation than adults would completely dominate every single kid in the world.
