What does water smell like? Did bipedal dinosaurs get back pain? Is my perception of time related to my heart rate? Does getting fresh air when you're sick actually doing anything?

Two Sams join Ceri and Hank in a team-based episode of Tangents. They talk about fitness challenges at Walt Disney World, perceptions of size, bizarre beasts, miniature organs, satellite launches, and the search for the smallest single-celled organism.

Deboki Chakravarti, an expert on animal extremities and their health implications, dives into the fascinating survival strategies of hibernating bears and Mexican cavefish. She explains how bears avoid blood clots during hibernation and the potential treatments this offers for humans. The conversation extends to the cavefish, revealing their unique adaptations to starvation and darkness that could inform fatty liver disease research. Deboki also humorously ponders the strange case of a mushroom growing on a frog, highlighting the complexities of defining species.
