To understand Behavioral Fitness we must first agree on a definition of fitness.
the condition of being physically fit and healthy
the quality of being suitable to fulfill a particular role or task
an organism’s ability to survive and reproduce in a particular environment
According to these widely accepted definitions of fitness, it follows that Behavioral Fitness would find one in a state of being mentally and emotionally fit and healthy. Moreover, the healthy mental state would enable, even propel an individual to complete roles and tasks, both small and large. Finally, Behavioral Fitness provides a foundation on which an individual, family, or even organization can gird itself for survival and position itself to flourish and grow.
