I will summarize the section from a book I have here titled The Complete Book of Chinese Health & Healing which mentions a study from 1980 showing that only 3 milligaus of energy was shown to affect cell health/growth. At the time 100 milligaus was often measurable from power lines. Instead of figuring out how to avoid or lower this radiation (cou-Tesla-gh) they simply up the 'allowable' amount for National Standards to the unhealthy amount already being radiated. With 3G, 4G and soon 5G towers belting out increasing amounts of radiation, I would extend the limits of cellphone use to adults as well as children and try to create a culture where we KNOW that our phones should BE OFF or AT LEAST 5 FEET AWAY FROM THE BODY when ON.
Just some extra thoughts. Found you on YouTube but are you also going to do DTube? great stuff, keep it up.
