Back to Methuselah; by George Bernard Shaw.

An attempt by one of the most intelligent thinkers, writers, people of last century to peep into future of evolution - beyond the present limits of where we are.

Life spans of longer than a century or two, youth and ability well into third century, or lives a millennium long with growing up and reproduction finished soon so the true vocation can be taken up, of thought and creation? Sensational, either way.
