Yes you are correct, and I do usually avoid falling into that trap. One great example I always use to illustrate the point you’re making is that Tiro, who was a slave of Cicero and the guy who developed the Latin shorthand writing we still use today, lived to be over 100. Now Tiro did act as Cicero’s secretary so wouldn’t have lived as harsh a life as a slave down the mines or anything like that, but a slave living to what we would still regard as a good age today over 2,000 years ago shows how little actual progress has been made in this regard.
