The Life of Riley is a phrase that has been used since the early 1900s to describe a life of ease and comfort. It is derived from a popular radio show of the same name which aired from 1944 to 1951. The show was about the adventures of a character named Riley, who was portrayed as a happy-go-lucky man who always managed to get out of difficult situations with ease. The phrase has since become a popular way to describe a life of luxury and comfort.
