On average, people probably do live longer lives now, however it is debateable as to whether the quality of those years is greater or lesser than in previous times. The answer to that question depends on what culture one examines in the present day, compared to what culture in some previous time, and also, what is the station in life of those being examined. Compare a New York apartment dweller of today to someone who lived in exactly the same apartment 125 years ago, who has the better quality of life? Compare an employee of White Castle to a medieval scullery maid, who has a better quality of life? Compare an inner city crack-baby to, say, a native American child of almost any tribe 400 years ago, who has the better life now? What was the average quality of life for a Viking, compared with, say, Arab tribesmen of the 18th century?
