Health problems

Electromagnetic fields are naturally present in the universe and the earth is part of the universe. When electricity was put to work at the beginning of last century it increased the presence of electromagnetic waves on earth. I have no idea what rate of increase can we talk about today, as we must add Cell phones, radios, TVs', GPR, computers, microwaves ... Nobody knows exactly what the effects on humans are of this increase and we should exert prudence. A modest and restricted use of cell phones is recommended, for instance, by those who are studying the effects of this gadget on brains: it seems that people who use cell phones with high frequency are subject to brain tumor 3 times more than people who don't. You may want to regularly change ear, or use headphones or just get rid of it !!!
