cholesterol or caffeine, being good or bad for you
I can't count the number of times if heard that the cholesterol in eggs will either kill you or make you live to be 100. I actually remember one time when I was a kid, my brother yelled at me that I was going to die if I ate the egg yolk on my plate. Kids believe what they hear on tv.
TIL my brother and Homer Simpson have more in common than I thought
It could be a story about cholesterol or caffeine, being good or bad for you, depending on the day. They have none of their own thoughts. The words are fed to them. Like politicians, these types aren't good thinkers, they are good actors.
