We establish that fear is a part of the human condition based upon our genetic predisposition. We have inherited fear from the beginning of human time because it was a form of protection in a dangerous world: the sabre-toothed tiger. Tennis is a symbolic fight which, while it is not life threatening, calls forth the same fear reaction. As pack animals, humans want to be higher on the ladder than their peers. Uncertainty, like the outcome of a match, can create the fear response. We talk about ways to combat fear, knowing that it cannot be completely eliminated.
