Those numbers work fine with what I said, they're fairly full adult lives. Life expectency has been rising over the past few decades with improvements to medical care, but only 50 years ago in the US, it was 70 years. If that's 'full', then the numbers above are 'fairly full', I think. Rome might be a touch short, but it's still much longer than the idea most people drop dead by 30.

Certainly in a sociological sense, most people consider the years 60+ to be twilight years where you're not living life to the fullest - whether it's true or not, that's the perception.
