1) Oahu is 44 miles long, 30 miles wide, 112 miles around and is the third-largest island in the Hawaiian chain of 132 islets, atolls and reefs stretching from kure atoll in the northwest to the big island of Hawaii in the southeast.
Origin. The phrase originated in the Irish/American community of the USA, in the early part of the 20th century. The first printed citation of it that I have found is from the Connecticut newspaper The Hartford Courant, December 1911 - in a piece headed ' Bullet Ends Life of Famous Wild Cow ':he best in the house is none too good for Reilly. So, while the idea of a notional Irishman living the high life was current in late 19th century America, the phrase 'the life of Riley' isn't found until the early 20th century.
A Oh, dear. The experts have been struggling with this one for decades but canât agree on who Riley might have been or how he managed to achieve his enviable existence of comfort and ease. He (that much is assumed) was certainly fictional but competing theories argue that he might have been either American or British.he first known examples of the phrase are American and strongly suggest that it started life in the US Army around the time America entered the First World War in 1917. Small-town newspapers frequently published letters sent home by soldiers from training camps in the US and from active service in France.
