This is a science and technology and educational video talking about honor. Hi, Vsauce Michael here, where is here and how much does it weight? Supposed to be as Michael, well what is the greatest honor. Let's begin our journey by looking at challenges and achievements wordy with honor. The first the physical ones being the fastest person in a marathon 42.195 kilometer, 26.2 miles is great but why stop there the ironman involves swimming 2.4 miles, racing on bicycle for 112 miles and then running an entire marathon. The winner did it in 8 hours three minutes 56 seconds. Beyond that thing to get mental.
