Reruns Help You Feel in Control:
It turns out, when you skip social situations to stay home and re-watch your favorite television shows there may be a real benefit. Research from the University of Buffalo published in The Guardian builds on the theory that, after periods of self-discipline, a person is more likely to give in to temptation later on. For example, if you go for a long run in the morning you might eat fast food for dinner.
To combat these slips of self-control humans can keep themselves happy by watching familiar television episodes. Psychologists say we think of these characters as friends or family. The familiarity helps us feel in control and keeps us happy and our discipline in line. So, go sit and re-watch "How I Met Your Mother" or "Friends." It's good for you. via The Guardian
