Average life expectancy in the United States is close to 80 years, 78.74 to be precise. Most of us don’t quite achieve octogenarian status. Life expectancy has seen a boost in the past century but regardless of how you look at it, we’re working with a relatively short period of time here. What is important is that with this brief moment, we enjoy our lives, take advantage of our opportunities, and lead a life we find happiness in.
