Let's consider.
Twenty-five--thirty-five--a man's in his prime then, they say--forty-five--a middle-aged man just entering politics--fifty-five--"died at the comparatively early age of fifty-five," according to the newspapers.

Bah! How these Christians funk death! Sixty-five--we're only getting on in years.

Seventy-five is just possible, though.

Great hell, cat O! fifty years more of solitary confinement in the dark! You'll die, and Beeton will die, and Torp will die, and Mai--everybody else will die, but I shall be alive and kicking with nothing to do.

I'm very sorry for myself.
