1.The name “funny bone” comes from the humerus bone, which connects the shoulder to the elbow. However, that’s not the source of the tingling sensation you feel when you bump your elbow just right. It’s actually the result of the humerus bone coming into contact with the ulnar nerve, which is responsible for telling the brain about feelings in the ring and pinky fingers.
2.All Blue eyed people come from the same ancestor. At least, they may share the same distant ancestor. After studying the DNA of blue-eyed individuals from Scandinavia, Turkey, Jordan, and India, Danish researchers found that they all had identical gene sequences for eye color. They believe this trait comes from a single individual, called the “founder,” whose genes mutated between 6,000 and 10,000 years ago. Before that, everyone had varying shades of brown eyes.
3.One strike of lighting contains enough energy to toast about 100,000 slices of bread. If you consider that each bolt of lightning contains more than 5 billion Joules of energy, then the average 1,000-watt, two-slice toaster could be powered for 84,000 minutes with just one strike. That’s just enough time to toast about 100,000 slices of bread, bagels, English muffins—whatever you prefer.
4.The blue whale is the largest animal on the planet, weighing up to 150 tons and measuring up to 90 feet long. Naturally, an animal this massive would have an equally huge heart. Roughly the size of a small car, the blue whale’s heart weighs about 1,300 pounds. To move blood through its colossal body and arteries, its heart beats so powerfully, you can hear it from two miles away. You just might miss it, though, as its heart only beats eight to 10 times per minute.
