A price as low as literally free can mean the economic equivalent of a free kitten -- I may get a free kitten, but then I have to deal with the consequences, with no exit strategy.

--- Bruce Sterling, Shaping Things, Ch. 9, p. 71

Jill B. told me about these two poems her father, Chippy Armstrong, used to quote:

A man is not old when his hair turns grey
A man is not old when his teeth decay
But a man is ready for his last long sleep
When his mind makes appointments, his body can't keep.

I burn my candle at both ends
It scarce can last the night
But oh my foes and oh my friends
It makes a lovely light.
