[Wear OS Q&A, Help & Troubleshooting] Toogoofy:
Well, one of the first rules of research is "Correlation does not equal Causation". Just take a look at the book Freakenomics for examples. So, because your knee hurt when a radio with BT was turned on doesn't mean it was literally the BT. How were the weather conditions? Were they all rainy days? Sunny days? Do you know? I'm not saying you are a liar I'm just saying there was no control to your conditions and one cannot know with certainty that this is the causation to your knee pain.

I'm not really worried about the whole radiation bit because thereare too many more dangerous things in the world that we should be paying attention to. Such as all of the E-waste we are making! That stuff going into our ground contaminating our water supply or people throwing old medication in the toilet these things cause some serious issues! Not to mention I have an implanted defibrillator that runs on wifi connected to my heart in my body! Have had it for five years and no growths yet!

Now looking at this were there any studies what so ever done as to what caused this. As in referencing my first sentence. Can it be proven that it was the "radiation" from their "living environments becoming grotesquely overrun with these emissions" or maybe something no less benign but not due to radiation but due to their habits? While this is aimed at those aged 20-24 it is logical to extrapolate this to the general population as well. Maybe not to the extent or it could be worse! But, it isn't due to radiation it is how it is being used affecting their mental health. So who is to say that being out in the woods not having these stressful interruptions or the need to be constantly connected didn't make their stress related illnesses go away? http://preview.tinyurl.com/7dclczr

Not, many people know about it but if you use the google scholar search engine you will get true academic results instead of conspiracy theory. I would also take a gander at some of these articles as well: As you can see this was taken from a vast array of specialties and from the Cancer Society. The only one I saw that could possibly but only minutely cause an issue could be the one where cell phone use caused the brain to intake more sugar on the side that the phone was on.
