The blue whale is the largest living creature—it’s even larger than most dinosaurs. The biggest blue whales can be over 100 feet in length and weigh more than 100 tons. Their hearts alone can weigh 1,300 pounds, and are the size of a small car. Unsurprisingly, blue whales therefore have enormous arteries, which pump blood through their massive hearts and into their vital organs. The arteries are so big that a full-size human could swim through them—not that you should try it.
Chewing gum stops you from crying while cutting onions.
We all know that chopping onions leads to many tears. That’s because the chemicals in onions travel through the air, and when they hit our nasal cavity or eyes, it causes us to tear up. You may have tried goggles or lighting candles, but did you know that chewing gum helps? That’s because the chomping encourages you to breathe through your mouth, so the onion’s chemicals won’t make it up your nasal passage.
One-quarter of all your bones are located in your feet.
There are 26 bones and 33 joints in each foot. That’s 52 bones in both feet, out of 206 total bones in your whole body, which is more than 25 percent. It may sound crazy at first, but think about it: Your feet support your weight and allow you to jump, run, and climb. Those bones and joints also allow your feet to absorb and release energy efficiently. It’s one of the reasons humans can outrun any other animal in an endurance race.
