875: New Year Goals, Testosterone Aggression, & Swallowed by a Whale

We are reviewing our year and our successes and failures with our New Year's Resolutions, and we're sharing our intentions for next year. We learn about a study by Robert Sapolsky that argues that testosterone does not increase aggression, but instead emphasizes existing tendencies and encourages people to behave in socially encouraged ways that already exist. But we have questions and concerns about his conclusions and wonder why when male animals of all species hit puberty they behave in ways that are highly aggressive in contrast to their pre-pubescent selves. We also hear about a man who claims he became trapped in the mouth of a humpback whale, and we find out why this situation was not out of the ordinary for him.
