Have device close to brain on left and right side is absolutly nuts
Ok so I presume you don't drive a car but ride a horse instead? You don't watch TV or listen to the radio because these devices emit harmful radiation? Internet is also dangerous because your wifi is frying your brain while you're typing this message? Don't forget about your phone and it's harmful GSM and 4G waves. Not even mentioning your house made of harmful concrete, fillers and plaster? Clothes, food etc etc etc
The OP should be more worried about sunlight esp UV radiation or high energy particles from deep space passing through them. Or naturally occurring radon gas that collects in many peoples homes.
