average lifespan of the elite roman class?

I'm not sure how you're getting better hygene out of those statistics...

As to emperors, how much of the adult population(in this case 15) reaches the age of 40? 1/3rd? So if you look at the emperors as a special group that survived to adulthood, 1/2 the emperors reaching the age of 40 is better than the general population of 1/3rd.

However, this is biased. Would be interesting to see that random people with the right genetics cna keep on trucking regardless.

Well first most of these emperors (and most Roman emperors period) became emperor AFTER the age of 30 to 40. Out of these 11 emperors, only Augustus and Lucius Varius became emperor before the age of 40, at ages 36 and 30 respectively. What I am saying is that the dead imperial princes isn't counted in these averages, and if they were the number would go down.

Second, out of 14 emperors who die of disease, 5 comes in the first 11 (45.4%). The rest of 9 comes in the last 28 (32%). In other words on average the chance for an emperor who dies of natural causes coming after Marcus Aurelius dying of disease is less than emperors coming before. Though yes it is very likely due to unrelated reasons, but those numbers still stand. If there isn't an increase in health care and sanitation, there isn't a decrease either until at least after the western empire fell.

Yes the elites of the time lived for a long time. King Tigran (Tigran the Great) died a natural death in his old age (late 70's early 80's)

Meanwhile Lucius Caesar, grandson of Augustus, died at age 18.
Augustus's line died out less than 70 years after his death.

Aye, Mithridates Eupatór was killed at 71, so these guys had a pretty long lives.
