True about idle time.
When I was in school as a kid I'd come home and analyze social situations while watching TV. I probably wouldn't have been able to recall what was happening in the show accurately.
Often before bed too. Once I feel I have a grasp on what happened I knock out. I put a big amount of effort into trying to figure things out.
These days, being a bit more secure in how things are for me, I knock out almost immediately like a baby, and watching commercials before say a football game I have to make fun of, mock, point out the inconsistencies just so I don't feel like my thoughts are being wasted on some useless brainwashing
