Self-Actualization
It is my thoughts that, when a person reaches a certain level of self-actualization, their other hierarchy of needs can become irrelevant. For example, Buddhist monks reach such a level in meditation and can resist all other needs - social, physiological etc. They can even get the point such as was displayed during one of the wars where out of protest they would sit and meditate under flames and burn to death. what is happening is they have come to a deep understanding of themselves and what motivates them and they rise above it.
