Masochism is sexy, human, reviled, worshiped, and delightfully bizarre. Deliberate and consensual pain has been with us for millennia, encompassing everyone from Black Plague flagellants to ballerinas dancing on broken bones to competitive eaters choking down hot peppers while they cry.

And Cowart would know: They are not just a researcher and science writer, they're an inveterate, high-sensation seeking masochist. In Hurts So Good, Cowart unveils how our minds and bodies find meaning and relief in pain--a quirk in our programming that drives discipline and innovation even as it threatens to swallow us whole.
