> Navy Seals talk about that being tired is just an emotion like feeling happy. Its all about your mindset. But it isn't really. Even taking that statement at face value you're still talking about people who are selected for their physical skills and then spend much of their prime training and preparing physically like their lives depended on it. Because it does. But they suck at many other things and they do have an excuse to not be able to do them. One person cannot "specialize" in too many things and downhill extreme mountain biking is not a thing to do half-assed without risking your well-being. Getting the skill and the physical strength to do it is both time consuming but more importantly very risky.
