99 percent of the population continue to use WiFi and other wireless devices without a second thought, but a growing number of people are becoming increasingly concerned with the health issues surrounding the use of these technologies. Didier Bellens happens to be one of these people. What makes Mr. Bellens different is that he also runs Belgacom, the largest telecommunications company in Belgium. His concern is such that not only has he chosen to do without WiFi on the 27th floor of Belgacom where his office is situated, he also chooses to do without a cell phone; only taking calls on the offices land line.
