- Ancient cultures like the Chinese, Egyptians, and Greeks practiced copromancy, diagnosing health based on feces.
- Modern science studies defecation to understand health issues like irritable bowel syndrome and gastrointestinal infections.
- Researchers studied feces from 34 mammalian species, finding herbivores produce 'floaters' and carnivores produce 'sinkers'.
- Defecation duration is surprisingly consistent across species, averaging around 12 seconds, despite large differences in volume.
- An ultra-thin layer of mucus in the large intestine enables efficient defecation, with bigger animals having thicker mucus for higher speeds.
- The study's findings helped design a diaper for astronauts by leveraging the viscosity of feces.
- Physics and mathematics can be applied to everyday phenomena, including defecation.
