- The French population yearly consumption of butter is around 18lbs per person. Amazing isn’t it considering it has one of the lowest numbers of heart problems.
2. Even before we are born we yawn. Studies have shown that even 11 week old Fetus yawns. The activity of yawning is said to be rejuvenating the brain.
3. Most pilots and copilots on major airlines are not allowed to eat the same food – to avoid the possibility of food poisoning sickening the entire flight crew. Also the risk of being killed in a plane crash for the average American is 1 in 11 million. The risk of being killed in a car accident is 1 in 5,000.
4. Some trees emit chemicals that attract enemies of their enemies. – Trees may look passive and helpless, but they’re savvier than they seem. Not only can they produce chemicals to combat leaf-eating insects, for instance, but some also send airborne chemical signals to each other, apparently warning nearby trees to prepare for an insect attack. Research has shown that a wide range of trees and other plants become more resistant to insects after receiving these signals.
Trees’ airborne signals can even convey information outside the plant kingdom. Some have been shown to attract predators and parasites that kill the insects, essentially letting an embattled tree call for backup. Research has mainly focused on chemicals that attract other arthropods, but as a 2013 study found, apple trees under attack by caterpillars release chemicals that attract caterpillar-eating birds.
5. Our feet are the home to about a quarter of all the bones in our bodies – There are 26 bones in each foot—one less than in each hand. When we’re born, those bones are mostly cartilage. The bones in our feet only completely harden around age 21.
