Facts

A grab bag of facts I find interesting - some space stuff, some gross body stuff. No real theme, just things I wanted to remember.

  2. Ceres is the only rounded body in the asteroid belt and it has a shiny spot on it that is ice and brine salts.
  3. Your blood can coagulate if you're at a high enough altitude for too long.
  4. If you stretched out the adult human digestive system end to end, it would be 30 feet long.
  5. The concept of the human self is perceived as a tension behind the eyes.
  6. The asteroid that killed the dinosaurs was between 6 and 9 miles across.

  8. The stomach produces a new layer of mucus every two weeks to protect itself, while it produces half a gallon of hydrochloric acid each day.
  9. Borborygmi describes the sounds your stomach makes when it rumbles. It can happen when you're hungry or even when you're not hungry. They sound loudest when your stomach is empty, as peristaltic waves move through your intestines.
