北京赛车pk10开奖直播 www.immadman.com 你都被哪些看似很有道理的谣言刷屏了呢?
Sleeping with wet hair doesn't give you a cold.
And no, you won't get cancer because you stood too close to your microwave.
Soap kills bacteria.
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.
Shaving hair makes it thicker.
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.
Dyeing your hair doesn't actually make it turn grey faster.
If you swallow a piece of gum, it will stay in your stomach for 7 years.
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.
Touching toads give you warts.
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.
The Great Wall of China can't actually be seen all that well from space.
即使在太空中的low orbit(低轨道)上飞行，你也很难用肉眼看到长城。除非你用zoom lense(望远镜)，但那样也不见得能看到。
Bats are blind.
Actually: Although bats use echolocation to orient in space, they also use night vision under certain light.
真相：英国谚语“像蝙蝠一样瞎”(As a blind as a bat.)让人们误以为蝙蝠没有视力，但其实多数蝙蝠都能看到一米以内的猎物。用声波定位后，它们也能在一定光线条件下通过夜视功能捕猎。
Hair and nails grow after death.
Actually: After a person dies, their skin becomes dehydrated and contracts, which creates the illusion of the growth of nails and hair.
Water conducts electricity.
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.
Antibiotics kill viruses.
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.
Sitting close to the TV worsens your eyesight.
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).
Coke dissolves teeth.
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.
