The population of the USA has gotten fatter and more out of shape since CD's came on the scene. The other digital devices seem to have made matters increasingly worse. There seems to be a definite connection between decreasing vinyl use and increasing waistline.
Also, the cell phone frequency of 2 GHz is very hazardous to human health, especially brain development. Children should not use them, and there are bans to that effect in several foreign countries. First brain development is affected, then can come cancer with continued exposure. Well proven by Air Force studies in strong high frequency radar fields. The politicians now voted into office is another indication of brain damage in the general population.
My old 1983 era Garrett metal detector acts up very strongly in town because of the cell phone noise field, and an old 1980's Hafler tuner was rendered inoperable by cell phone noise. The metal detector works perfectly in the countryside away from cell phone interference.
If you think your brain and your health are not affected as well, then you are already affected quite a bit.
My college degree is in biomedical instrumentation, so I have a better-than-average knowledge of what EMI fields do to your health. European cars are designed with EMI fields in mind, while most American cars fail the European EMI standards by a gross amount. I have met people at an environmental health clinic totally screwed up by EMI exposure. Digital gear that leaks high frequency radiation truly is hazardous to your health, so be careful. American FCC standards relate to interference with other communication devices and they are in no way connected to a human health study.
My dog likes to lay in my lap when I listen to vinyl, but he generally leaves the room after a while when digital devices come into play. Our dogs and cats have been warning us about digital for years. I am convinced that some dogs are very tuned into any disturbances in the electromagnetic physical medium, as my dog seems to know what people are thinking and he never warms up to certain people who are indeed troublemakers. Brainwaves create a disturbance in the EMI field (which is why biomedical instrumentation picks them up) just as they are affected by EMI fields.
If I read something on the internet that really disturbs me and gets me angry, then without saying a word to him my dog will get up and leave the room, as he knows what I am thinking and doesn't want to be around an angry me. Then I know it's time to cool down and go grab a shot of brandy or something.
