Could you explain the exact connection, though? I don't understand what's funny about it. It'd be like a book written 100 years ago saying "humans can fly", and then in 2200 someone invents a cheap portable jetpack. If you lived in 2200, would you say "it's funny" that that old book mentioned flying and look, here we are, flying? Plenty of other old texts depict long-lived humans as well. It's probably been a fantasy among humans for many thousands of years.
