The reality is, cellphones have to be used safely. They are today like cars and trucks - we can't live without them, but we certainly wouldn't give a car or truck to a toddler to drive. Why are we thinking it's perfectly okay to give a device that the World Health Organization has said is a "possible human carcinogen" to infants and toddlers, and for that matter, schoolchildren?

The younger a cell, the faster it grows, the more vulnerable it is to damage.

We know that drugs, sex and rock and roll stimulates something called dopamine in the brain. So do videogames. Dopamine is something that we crave.
