Dear Luke,
Your message reminds me of a conversation in the course of which
somebody said that coffee was a slow poison. An old man agreed with him,
saying that it was indeed a very slow poison, because he had been
drinking it for the last 90 years. Roasted coffee, by the way, is a
torrefied product.
Yours
