As for the time thing, these are a couple factors that I'm pulling out of my ass as I type them.
I don't watch much tv apart from sports, so if there isn't a good game on and I'm home, my activity options are few. If I'm home with the kids that night, once they go to bed I have to occupy my next few hours in some way, and usually that's with a drink and a book
I also am reading several books at once, and they're stashed around the house so wherever I am, there's probably a book within reach. So I have my bathroom book, bedside table book, kitchen book, and living room book.
And also, I read books on subjects that I'm really interested in, which consists of music, sports, business, politics, culture, etc., so the prospect of, say, spending the night sipping scotch and reading a critical look at Putin's life sounds great.
