That's a very good point... and are we really awake when we watch T.V.? Or are we in some type of suggestive state?

I wrote the above and then did some googling. Found this article: https://www.fastcompany.com/3060491/what-happened-to-my-brai.... I don't know how reputable it is, but here's a quote relevant to this discussion:

"There have been EEG studies that demonstrate that television watching converts the brain from beta wave activity to alpha waves, which are associated with a daydreaming state, and a reduced use of critical thinking skills."
