If I ask you to summarise your life till now what do you think you will recollect? Experiences and memories. But what kind exactly! Either the best or the worst because the regular ones would not be that significant to make an impression on your mind (hold on, we are getting there). Let’s say we call these best and worst memories as peaks. While you are covering the peak points about your life, you never miss telling the ending because that is exactly what matters the most.
