The most dangerous thing in a fight is a thinking man, even when he's somewhat fatigued, where a certain mental toughness remains. This is one of the reasons why selection processes for more elite military units incorporate lots of sleep deprivation over weeks, not just a few days. Most people can't continue to function, and performance of basic tasks deteriorates, while the mentally tough drive on and thrive in these conditions, still able to perform higher levels of physical exertion, decision-making, while avoiding injury. Staying in the moment is your friend.
