Old Wives' Tales Proven Untrue

We all grew up with sayings that were intended to frighten us into being good or convince us to eat better．Looking back, some of these childhood proverbs don’t even make much sense．（Ever hear the claim that swallowed gum stays in your stomach for seven years? Uh-huh, sure．）However, there are quite a few out there that people still believe in．That's why we decided to investigate some common old wives' tales to see how they hold up under scientific scrutiny．From the moon's affect on crimes to the true causes of colds, this list is sure to surprise even the most enlightened among you．

小题1:     

False: Countless kids were scared into thinking that if they went back in the water less than 60 minutes after eating, they would suddenly cramp up （the muscles get suddenly tightened） and drown．But according to MayoClinic．com, it's perfectly safe to swim after you eat a light meal or snack． The site does recommend taking a short break after eating a big meal, however, not because of cramping, but due to extreme lack of energy． As is known to us all, after eating, more of our blood goes to help the digestive system．

小题2:      

Partially True: This saying has been around since before the discovery of an apple's vital nutrients: Vitamin C and polyphenols．Regardless, the core of the matter is that while this fruit will help keep you well, it's not always enough to keep you out of the medical danger zone; When you're ill, your body requires nutrients from all the different types of food in a well-balanced diet, including fruits, vegetables, yogurt, protein and, of course, chicken soup．Only one kind of specific fruit or food can not solve all the problems．

小题3:      

False: According to the National Weather Service, lightning can strike the same place numerous times, especially if it's a tall, pointed and isolated object． For example, the EmPire State Building, a skyscraper on Fifth Avenue, New York City, USA, which was for long the tallest building in the world, 'is hit an average of 25 times a year． That is the reason why it was once used as a lightning laboratory． Lightning often strikes more than three miles from the thunderstorm and laughs at two  inches of rubber!

小题4:      

False: Neither wet nor dry hair significantly increases your chances of getting sick．WebM  D.com says colds are solely caused when viruses are passed from one person to another, so you should be more concerned with how often you wash your hands, not your hair． A proper way to keep healthy is to develop good personal habits of life．Prevention is always the best cure, better than any drug and treatment．

小题5:      

False: Many interesting things are thought to increase during a full moon emergency room visits, accidents, ability to have babies, werewolves．Almost all these phenomena are attributed to the Lunar Effect, which tries to link unusual, unbelievable, or unacceptable behavior and the phases of the moon． However, according to myth-buster and syndicated columnist, Cecil Adams, there is no truth at all behind the theory．
