If I have to worry about cell phones & microwaves (what about your microwave ovens), then there is no point in going outside. Most places I go to now days have wifi, 90+% of everyone I know has a cell phone, for this study to say stay away from people who have one is ridiculous - it's not going to happen.
If I am going to die - which can happen anytime in your life be it accident, purposely or naturally, it's going to happen, I am not going to stop living life just to try to live longer. When my time comes it comes.
It's like that little joke,
aren't all of these health nuts lying in their hospital death bed dying of nothing going to feel foolish!
