I think one that I know will be around for my life is "quiet time" after work. When I get home, I want just an hour to just lounge around in silence and read the news or sf. It recharges me for whatever I need to do in the evening.
In Mad Men there is one scene where Bettie has a friend over, and Don comes home, says hello, then goes upstairs, and Bettie tells her friend "He always wants some time alone work." I understood that immediately.
