First records are in early 1900s so very unlikely, more than likely due to levels of streas and longer living

It's just that We all have a electromagnetic field and are an antenna to a degree, it feels like someone's turning a dial to mess with our nervous system which is also just electrical signals!
I used to build electric guitars for a living and when you over wound the pickup with fine cooper wire it gives you a higher gain/distortion sound.

Mine started in 1953 when I was 4. We got our first TV in 1958, so probably not. In 1956 I had such severe muscle spasms in my legs that a doctor was called. It's possible that it was because at the time there was a polio pandemic. Universal medical coverage didn't show up until 1966 in Canada.
