Pompano Beach, FL
I've seen some of the consequences of carrying a cell phone
in pants pockets. Two affected areas on the leg, lined up with parts of the Amps/GSM phone. The top of the cell phone antenna, and the base of the cell phone. Initially they appeared to be a mild form of RF burns.
Needless to say, I no longer carry a cell phone in anywhere near my skin.
My android normally resides in one of the outer pockets of my knapsack(while biking).
(It also receives a better GPS signal in that outer pocket.)
When I'm at home it sits next to Bluetooth gateway, that links it my land line phones.
Note: Mere Milli-volts can shift an equilibrium in organically catalyzed reaction.
Care to guess what category of catalyst dominates chemical reactions inside living cells??
