Interesting:
https://www.youtube.com/watch?v=F9bdU_uw2Dcseems she was watching a lot of youtube on a laptop as well as making the videos and she got ES to the point the couldn't make videos are more. Further adding to what I said in other threads that downloading and watching youtube are high EMF activities both for wifi and for CPU power..
I just compared playing a youtube with playing a vimeo and the EMF on my laptop is lower while playing vimeo than youtube.. although I was comparing by speaker and peak V/m, I'll have to do a M field test as well, but it sounds maybe 30% less.
I think a lot of youtube is a waste of time.. use it with caution, especially if you have ES!..
