On cell phones give you cancer

apply some risk analysis to the subject: the risk of getting cancer from cell phones must be, at most, vanishingly small vs the opportunity of a cell phone saving your life.
This, amongst countless others, shows that probability of having your life saved is measurably real as opposed to possibly getter cancer from welding a cellphone to your ear.
Conclusion? Cellphones are a benefit to society (if not conducive to having a quiet coffee in your favority cafe) keep an eye on the research but FFS stop the media scare stories.
