SUMMARY
- Goose bumps form when tiny muscles at the base of hair follicles contract. In the animal kingdom, this helps them warm up faster by standing each hair on end and creating a sort of insulation.
- Other people hear the soundwaves of your voice coming only through the air, and a recording also contains just these sounds. Yet the way we hear our own voices is a combination of the regular sounds and the low-frequency sounds conducted by the bones of our skulls.
- When something extremely cold touches the roof of your mouth, the nerve center located there tends to overreact.
- In both cases, the sun’s UV rays break down melanin, which is the pigment responsible for the color of your hair and skin. The difference is in the fact that hair is made up of dead cells while skin cells are alive.
- Kids are only starting to get acquainted with the world around them, and their memory has to collect more data. So their year contains more new and unfamiliar "events" than that of a grown-up.
- The pigeons hanging out in urban areas have developed a habit of settling on the rocky landscape where there are no trees. It means they didn’t inherit the tree-perching reflex of their rural or jungle relatives.
- Dust is actually gray, but the tiny size of its particles prevents us from seeing its true color.
- Dust is actually gray, but the tiny size of its particles prevents us from seeing its true color.
- When you sleep, it optimizes the synapses in your brain. What this means is that your memories solidify and the tidbits of information you’ve gotten throughout the day move from your short-term to your long-term memory.
