濕發睡覺不會引發感冒。
簡單來說，感冒是由於virus(病毒)引起的。

And no, you won't get cancer because you stood too close to your microwave.
你離微波爐太近並不會得癌症。
微波爐的radiation(輻射)是不會電離化的，也就是說它不會改變我們的身體中的molecular structure(分子結構)。

Soap kills bacteria.
肥皂殺菌
Actually: Soap only washes bacteria off without killing it.So why does soap work? Washing your hands with soap rids them of grease, which is the breeding ground for bacteria.
真相：肥皂只能洗掉細菌而不能殺死它們。那麼問題來了，為什麼要用肥皂?敲黑板劃重點了!因為肥皂洗掉你手上的油脂，而油脂正是細菌的親媽。

Shaving hair makes it thicker.
頭髮越剪越多
Actually: Shaving facial or body hair gives the hair a blunt tip. The tip might feel coarse or"stubbly" for a time as it grows out. During this phase, the hair might be more noticeable and perhaps appear darker or thicker— but it's not.
真相：不管是剃鬚還是剪髮，發梢都會變成一個鈍角的平面。毛髮再次生長時，粗糙的質感會讓你感覺毛髮變得更黑更多，但這只是你的錯覺。
5
Dyeing your hair doesn't actually make it turn grey faster.
染髮並不會加速頭髮變灰。
頭髮由黑變灰是由於黑色素減退導致，染髮並不會影響這一生理過程，但是生活方式、壓力、和其他因素會影響。
6
If you swallow a piece of gum, it will stay in your stomach for7 years.
誤吞的口香糖會在胃裡住七年。
Actually: Although the viscous base of chewing gum is not susceptible to gastric juice and does not dissolve in it, it is excreted from the body naturally through muscular contractions of the stomach.
真相：咀嚼口香糖產生的粘性物質不會溶解在胃液中，而是會通過胃部肌肉收縮自然排出體外。
7
Touching toads give you warts.
摸過蟾蜍會長疣
Actually: Warts are benign growths caused by the human papilloma virus. You can pick it up in public places or through contact with a sick person.
真相：蟾蜍和青蛙不會傳染疣給人類。疣是乳頭狀瘤病毒導致的良性增生，人類只有在公共場所活動或接觸病人後才會感染疣。

The Great Wall of China can't actually be seen all that well from space.
在太空中看地球是看不到一整條長城的。
即使在太空中的low orbit(低軌道)上飛行，你也很難用肉眼看到長城。除非你用zoom lense(望遠鏡)，但那樣也不見得能看到。
9
Bats are blind.
蝙蝠什麼都看不見
Actually: Although bats use echolocation to orient in space, they also use night vision under certain light.
真相：英國諺語「像蝙蝠一樣瞎」(As a blind as a bat.)讓人們誤以為蝙蝠沒有視力，但其實多數蝙蝠都能看到一米以內的獵物。用聲波定位後，它們也能在一定光線條件下通過夜視功能捕獵。
10
Hair and nails grow after death.
人死後頭髮和指甲還在長
Actually: After a person dies, their skin becomes dehydrated and contracts, which creates the illusion of the growth of nails and hair.
真相：人死後，皮膚開始脫水和收縮，所以會給人頭髮和指甲還在長的錯覺。
11
Water conducts electricity.
水能導電
Actually: What conducts electricity are minerals with positively and negatively charged particles, which water molecules themselves don' t have. Therefore, distilled water, because of the lack of impurities in it, does not conduct electricity.
真相：礦物質帶有正電荷和負電荷所以能導電，而水分子本身並沒有。所以蒸餾水無法導電，因為它缺乏雜質原子。
12
Antibiotics kill viruses.
抗生素能殺死病毒
Actually: Antibiotics only deal with bacteria, killing them or stopping their reproduction but don't kill viruses. So it is important to find out whether the disease is caused by the bacteria or virus.
真相：抗生素不能殺死病毒，只能殺菌或阻止細菌繁殖。因此，生病時要搞清楚疾病是由細菌引起的，還是病毒引起的，這很重要。
13
Sitting close to the TV worsens your eyesight.
看電視離太近對眼睛不好
Actually: There is no evidence for this. However, sitting close to and watching too much TV can cause eyestrain(as many office workers can tell you after a longday staring at their computer screens).
真相：目前還沒有證據證明看電視離得太近真的對眼睛不好。不過港真，離得太近或長時間看電視會引起眼部疲勞，這是天天面對電腦屏幕的上班族的辛酸啊!
14
Coke dissolves teeth.
可樂會溶解牙齒
Actually: The myth that a tooth placed in a glass of Coke will dissolve overnight has been perpetuated for years. This is supposedly due to the presence of three acids— phosphoric, citric, and carbonic— in the drink. However, these can be found in many beverages.
真相：多年來都流傳著可樂能在一夜間溶解掉牙齒的神話，現在這個神話要瞬間崩塌了。之所以會有這種說法是因為可樂里有磷酸、檸檬酸和碳酸。不過很多飲料都含有這些物質，所以喝完飲料記得漱口哦!
