The study of any workplace is the study of how people work, and the study of how a person works begins with how her brains works.

These are mammalian capacities, as compared to fight-or-flight urges, which are the reptilian functions of the brain. Again, a more comprehensive explanation as to why your office needs, collectively, to embrace its inner mammal.
