Sol- a day ago

I remember the book "Algorithms to Live By" actually also uses finding a life partner as a fun, if perhaps unrealistic, example of applying the secretary problem.

As far as I remember, it jokingly assumes that one's active dating period might be ages 20-40 and then applying the optimal solution from the secretary problem means that you should calibrate your expectations until age 27 (assuming regular dating of course) and then immediately marry the next best person that exceeds this threshold.
