Robert Sapolsky; The Uniqueness of Humans
We all have some measure of stress, and Robert Sapolsky explores its causes as well as its effects on our bodies (his lab was among the first to document the damage that stress can do to our hippocampus). Every year, he goes to Kenya to visit a population of wild baboons, who experience stress very similarly to humans. By measuring hormone levels and stress-related diseases in each primate, he determines their relative stress, looking for patterns in personality and social behavior that might contribute. These exercises have given Sapolsky amazing insight into all primate social behavior, including our own.
Just watch it, okay
