After injuring my hand, I thought about all the different reasons why the injury occurred. Beyond the obvious procedural items, there was one cause I found interesting. In sports one of the items they coach is understanding the relationship between energy level and awareness. That is because peak performance is not about maximum energy or effort at all times. It is about knowing what level of energy is appropriate for the given job because, as you energy level increases, the range of your awareness shrinks. 

For example, in football, a pass rusher can raise their energy level because the only point of focus is to get to the quarterback as fast as possible. On the other hand, a quarterback cannot do that because they need to see the full field of play. That is why the best quarterbacks often seem "relaxed" or calm in the field of play. It is essential for them to control their energy level and see the full field of play. So, where is the connection to safety?
