Cell phones have been popular in Japan since the early 1990s, but it was not until 1999 that their use really took off. The age of cell phones has emerged, but with it come problems.
Cell phones are used on buses and trains, in restaurants, and in all areas of life. They causeproblems when they ring during meetings, concerts, wedding, or even funerals. What’s more, people speak loudly in public, and students read and text messages during lessons. More seriously, when a cell phone is used near a person using a pacemaker to regulate his hearbeat, its radio waves may interfere with the functioning of the pacemaker.
Now, something is being done to solve these problems. In many places, new technology is being used to block cell phone calls. Airline passengers are requested to stop using cell phones while on board. Concert halls ask their audience to switch their phones to the silent mode. However, phone users fear that if they do not answer their phones, they will lose valuable business opportunities. That’s why many do not turn off their phones even when they are asked to.
