A common trend in recent human history is this: we think something isn’t harmful, but find out it really is years after its introduction into the global marketplace. Cigarettes are the most obvious example, but the use of cell phones may very well become just as vilified.
We now live in an era where children born today are introduced to cell phones and other electronics almost instantly, and the very first cell phone generation is now reaching adulthood. They haven’t been around long enough for us to see any harmful consequences fully materialize, but there is more than enough information out there validating what seem to be innumerable concerns over cellphone usage.
