  1. 21ST CENTURY MYTHS • Alex Kenan

  2. Myth • A common misconception, an error.

  3. Common Myth • An erroneous belief pertaining to every person, either created to deter someone from doing an action, or to encourage this person to do an action.

  4. 20. Bless you • THE MYTH: If you stay outdoors on cold, rainy days, you can contract sicknesses ranging from colds to pneumonia.

  5. 20. Bless you • THE TRUTH: Germs are spread by touching the eyes, nose, and mouth, when germs are on your fingers, or by inhaling droplets of germs expelled by a sneeze. Cold weather does allow germs to survive longer, but cold weather and viruses are not connected. As a matter of fact, people who stay inside are in closer contact with each other for longer periods of time than they would be in the summer.

  6. 19. Most of your body heat is lost from your head • THE MYTH: Your body loses most of the heat through your head.

  7. 19. Most of your body heat is lost from your head • THE TRUTH: In the official military study, the soldiers were wearing heavy winter clothing, but their heads were uncovered. This lead to their heads losing the most heat. If this clothing is more equally distributed, your head loses only 10% of your total body heat.

  8. 18. Scratching poison ivy will spread it • THE MYTH: If you scratch poison ivy, you get the urushiol (the poison ivy oil) on your fingers, and the next body part you touch will contract poison ivy.

  9. 18. Scratching poison ivy will spread it • THE TRUTH: By the time the rash appears, the urushiol has more than likely rubbed off, and the rash that appears later was merely a delayed reaction. Rubbing only irritates the rash, but does not spread it.

  10. 17. PENSIVE ABOUT CENTS? • THE MYTH: Dropping a penny from a tall building can kill a pedestrian.

  11. 17. PENSIVE ABOUT CENTS? • THE TRUTH: A penny is not aerodynamic enough to accelerate to a “killing” speed, and there are winds that hit the building and are directed upwards, further slowing down the penny.

  12. 16. The five second rule • THE MYTH: If you drop a piece of food on the ground, you have five seconds before any germs will infest it.

  13. 16. The five second rule • THE TRUTH: Germs have already infested your piece of food, even if it has only been on the ground for a second.

  14. 15. Wake up, sleepy head • THE MYTH: Doctors advise parents to never wake a sleepwalker, lest they die of a heart attack from the shock of waking up.

  15. 15. Wake up, sleepy head • THE TRUTH: There have been no reported cases of death by awakening, although there could be unreported deaths.

  16. 14. What’s that over yawnder • THE MYTH: Yawning is contagious.

  17. 14. What’s that over yawnder • THE TRUTH: The prevailing theory of why people yawn is to disperse build-ups of carbon dioxide. Therefore, high carbon dioxide levels will likely affect several people in proximity. So it is likely that one person’s yawn could make other people involuntarily mimic the yawn.

  18. 13. THE GREAT WALL • THE MYTH: The Great Wall of China is the only man made object that can be seen from space.

  19. 13. THE GREAT WALL • THE TRUTH: Nothing detailed can be seen from space. To be able to see the Great Wall, other objects such as Mount Rushmore, and The Sphinx, would be seen as well.

  20. 12. The itsy-bitsy spider • THE MYTH: You swallow eight spiders a year.

  21. 12. The itsy-bitsy spider • THE TRUTH: Even in your sleep, you move enough to scare, or at the very least, deter, most spiders.

  22. 11. GOLDEN LIARS • THE MYTH: Goldfish have a three-second memory.

  23. 11. GOLDEN LIARS • THE TRUTH: Goldfish have been taught to navigate mazes and associate items with food.

  24. 10. AIRCRAFTED TALES • THE MYTH: A rapid decompression in an airplane (a window breaks opens at 35,000 feet, for example) will cause a black hole scenario, sucking every passenger out of the aircraft and destroying the plane in the process.

  25. 10. AIRCRAFTED TALES • THE TRUTH: The space allotted for windows is small enough that a pilot would have enough time to descend below 10,000 feet, where explosive decompression is not possible, before the plane could break up.

  26. 9. READ FOR THOUGHT? • THE MYTH: Reading in poor light ruins your eyesight.

  27. 9. READ FOR THOUGHT? • THE TRUTH: Eyes are designed to be used, so they may be strained, but not permanently damaged by poor lighting.

  28. 8. Seven years has gone by so quickly • THE MYTH: It takes gum seven years to pass through your digestive system.

  29. 8. Seven years has gone by so quickly • THE TRUTH: Your intestines siphon any and all nutrients from the food you eat, so any waste is merely passed through your body as a solid and exits your body roughly two days later.

  30. 7. EYE WON’T WEAR THOSE • THE MYTH: Wearing someone else’s glasses will damage your own eyesight.

  31. 7. EYE WON’T WEAR THOSE • THE TRUTH: Duration is key here. For a few minutes or days, nothing will happen. But extended out a few years, and your eyesight will be affected.

  32. 6. You need to wait 30 more minutes.... • THE MYTH: You must wait at least thirty minutes, preferably one hour, after eating to swim. Because your body diverts blood to aid digestion, swimming too soon can give you life-threatening cramps.

  33. 6. You need to wait 30 more minutes.... • THE TRUTH: Blood is diverted for digesting, and the fear is that too much blood is diverted. However, not enough blood is rerouted to cause a major cramp that could lead to drowning.

  34. 5. Dehydrationing • THE MYTH: In a normal diet, you should drink a minimum of eight glasses of water a day.

  35. 5. Dehydrationing • THE TRUTH: About seven cups of water are consumed by eating regular food daily, which satisfies most of the required water intake.

  36. 4. Water You Waiting For? • THE MYTH: If you are thirsty you are already severely dehydrated.

  37. 4. Water You Waiting For? • THE TRUTH: The body’s mechanism for indicating thirst is to be thirsty, so being thirsty is not a sign of severe dehydration.

  38. 3. EYE SPY • THE MYTH: Crossing your eyes will cause them to stay that way.

  39. 3. EYE SPY • THE TRUTH: Crossing your eyes uses an often-idle muscle, so it will feel weird, but this muscle will not freeze up and keep your eyes crossed involuntarily.

  40. 2. POP • THE MYTH: Cracking your knuckles causes arthritis.

  41. 2. POP • THE TRUTH: The popping sound is caused by bubbles in the cartilage moving and popping. This does not cause arthritis, but it does erode the cartilage over time.

  42. 1. More Aircrafted Tales • THE MYTH: When electronics are turned on below 10,000 feet, they will interfere with the airplane’s navigation equipment.

  43. 1. More Aircrafted TAles • THE TRUTH: The fear is that there is electromagnetic interference, and it will render standard navigation equipment useless. However, aircraft have triple- and quadruple redundant systems designed to combat this. These systems have been shown to be highly, but not 100%, effective.
