Mary Roach gave a TED talk on "10 Things You Didn't Know About Orgasm". She aimed to engage the audience with shocking yet funny facts about orgasm. Some of the facts included that orgasms can be experienced when brain dead, they can cure hiccups, and pig farmers sexually stimulate female pigs to increase fertility. While the content was interesting, Roach's delivery was somewhat flat and rehearsed, lacking dynamism. The review suggests connecting with the audience through personal stories, energy, and topic-related jokes to better deliver interesting content.
