Most sheeple do not read books
We should always remain skeptical about the massive media, government dictates & advertising wave that carries millions along the stream of rubbish into the darkness of ignorance.
The late Physicist Dr. Carl Sagan once demonstrated (in his COSMOS 1980 show) that if we read a book, everyday for the average human lifespan, we will have really read but only a minuscule of nearly nothing regarding important knowledge that is out there, (and that was before the Internet era!). So, choose wisely what you read because there just isn't enough time to gain significant knowledge in this life. It's your choice, just like eating. We choose both kinds of nourishment we put into our bodies and minds.
Avoid the mass media and what it recommends we do what things posses value and how to live your life. Most folks are locked in and just flowing along. Was your ex-girlfriend one of those Grogs?
Carl Sagan was right in so many ways. Stay alert, your freedom depends on it.
