Ups and downs are very simple facts of life anybody can expect of at any point of time throughout their living days. Many people like to coin the phrase "Life is a roller coaster", which isn't too far from the truth.

         From where I see it, my point of view would see that the "ups" of our lives are derivative from the "downs", basically meaning we need to have anti-climax events to happen to us before/after we experience fulfilling happy situations, just so that we appreciate what enjoyable moments we have had.

For example Don't you agree?
