  1. Humans Are Beating Horses in the Race to Get Faster

    Athletics records have been consistently hurdled over the past 50 years, while horse-racing times have flatlined — but why is man winning the race to get faster? It seems that while thoroughbred horses had practically reached perfection by the 1940s, humans have been steadily improving over the last 150 years. More protein in our diets has increased muscle development and height, while better gear has aided aerodynamics and grip. Though we may be speeding up, we’re still outsprinted by horses. Usain Bolt can only reach speeds of 27 mph, well shy of the 43 mph of a top racehorse.
