What´s Your Number?

A cell phone, or mobile, is an electronic device used to make calls from where ever you are, instead of using a home phone, that just works inside your home. A cell doesn't need to be conected or to be in a certain range of a base line, it can work everywhere, and all it needs is charge. Now the cells are usually smaller than your hand, unlike the first cells of history, that were the size of a brick. Now they're 3 inches long and 5 inches tall, normally. It also weights around 4 ounces. At first they were used just to make calls, but as time cahnges, it has been changing too, now a cell has a camera to take pictures and video, it can be used to get online (updating your facebook, using twitter, watching your mail, download music or videos, etc.), these cells are now called smartphones. Lately, the phones are listed, by the World Health Organization, as a possible carcinogen, which is a category of the dangers of chemical exposure, because it's believed that the phones emit radioactivity waves that, eventually, are really dangerous to our health. So use your phone, but don't do excessive use.
