english: All of our science comes from the fact that our ancestors were able to do something extraordinary every day, which was just rely on their naked feet and legs to run long distances.
non_english: naši predkovia vedeli spraviť niečo obdivuhodné každý deň, a spoliehali sa pri tom iba na holé päty a nohy pri behu na dlhé trate. Tak ako by sme sa tam mohli vrátiť?
