When it was found that Earth is round , this idea was found to be wrong
Life is full of commonly believed myths and people’s behavior is often guided by those truisms. But are they true? Some are, but many are as false as the idea that tax breaks magically create jobs.
Here are 14 common beliefs that turn out to be fiction; and five more that scientists have discovered are surprisingly true.

1. Talking on your cell phone will give you cancer.
There has been lots of talk over the years about how the radiation from cell phones may be causing brain tumors. As it turns out, not so much. An annual report from the Presidents Cancer Panel found no evidence to support the link between cell phones and malignancies. In fact, while talking on cell phones has increased by sixfold since 1991, the number of brain cancer incidences has actually dropped by half.
2. Holding your laptop on your lap will make you sterile.
This myth grew out of a study by Argentinian researchers in 2011 which seemed to indicate that the electromagnetic radiation from the wifi signal damaged the sperm in a man’s testes. Chalk this one up to media sensationalism. The truth is that the researchers themselves admitted that the setup was artificial in nature. The laptops were placed on laps for four straight hours, a somewhat rare scenario. Not only that, but the normal angle a man would sit would place the computer not on his testes, but rather on his thighs. In rebuking the study, French cancer researchers remarked, “Genotoxicity of radio frequencies is not a matter of opinion: Radio frequency energy absorption cannot break DNA molecules.”
