What a wonderful fable. I enjoyed reading it and wish there was more research occuring in this field. Still, I'm impressed from what I hear in the news from time to time.
Yes it's so good. An amazing way to give a new perspective on life and death as we know it _today_ imho. Strong emphasis on _today_ because life expectancy, healthy life expectancy and death are already really different from some time ago. https://en.m.wikipedia.org/wiki/Life_expectancy
So for instance in modern history, of the 15 key Founding Fathers, 7 lived to at least 80 years old: John Adams, John Quincy Adams, Samuel Adams, Jefferson, Madison, Franklin, John Jay. John Adams himself lived to 90. The youngest to die were Hamilton who died in a duel, and John Hancock who died of gout of an undocumented cause - it can be caused by excessive alcohol consumption. All the others lived into their 60s and 70s.
It's the same as you go back further into history. Look up basically any Ancient Greek you're familiar with, and you'll see most lived to about the same amount of time we do now a days, sometimes quite a bit longer. For instance Hippocrates, of the Hippocratic Oath, lived to 90 back in the 4th century BC. The common claim there is a survivorship bias, but that's not really true - because most of these individuals made their mark on history decades before they finally died. In other words had e.g. Plato died when he was 50 instead of 80, he still would be known today.
