Back in the 1950s, an economist named Franco Modigliani, who went on to win the Nobel Prize, posited something that came to be known as the Life-Cycle Hypothesis (LCH)—an idea about how people manage their spending and saving to try to get the most from their money across their life span. He basically said that making the most of your money in the course of your life requires that, as another economist put it, “wealth will decline to zero by the date of death.”
