One common theme Ive read in TMS books are things like "People worked on typewriters in the 20s and 40s for hours and hours a day with no pain and now all of a sudden starting in the 80s RSI is a huge thing for everyone." Another example would be scholars, people who read tons of books, I dont remember reading anything about people in the past who did lots of near work like reading and stuff having eye strain issues which is now called CVS. They blame it on the computer now causing the eye strain. The question is how come this has started only in the past 30 years or so? What changed in society that created mind body epidemics like this that wasn't there previously? Was it the internet and the easy access to information that people could talk about the pain they were having and start exhibiting it? I remember reading on another forum a while ago that a guy wouldn't sit next to a radio thing on the ceiling at his job because he thought it gave off radiation. He was deathly afraid of this thing and the technician who put it in said its absolutely impossible for it to give off radiation but this guy was convinced positively of it. There is a book called something like "Total Health at the computer" that i've read in the past that talks about computer vision syndrome and its from 1993... i had never heard about this book at all and ive been working on the computer for around 17 years until i started getting eye strain problems. i didn't even know this term CVS existed until this all started. So I think its the media and the internet that spreads these problems/syndromes like wildfire.. all you have to read is on one forum somebody else got pain from doing an activity, like working on the computer, and then you start worrying about it and begin to exhibit the symptoms yourself. What do you guys think about all this? Why now and not in the past?
