Having computational perspectives in life can help design your lives so nicely! Here's a solid example which many singles can use, thanks to Scott for including the dating protocol in his lecture 18 :)
This can not only help in dating but also classifying people into jerks and reasonable ones. If the dating protocol does not work then the conclusion is at least one of them is a jerk, hypocrite, liar or whatever in which case you at least have a solid reason not to worry. Of course it is not necessary that you won't worry though!
