Episode notes
Block Onion Vapours With Goggles
- Wear sealed goggles when chopping large amounts of onions to stop the irritating chemical reaching your cornea.

- Smaller animals often perceive time more finely because their nervous systems process visual information faster.
- Eagles can resolve ~120 images per second while humans blur motion past ~15–20 frames per second.
