thanks, Colin. I so love your witty take on this subject and your, admittedly anecdotal, evidence. This "everything in moderation, including moderation" was a new one to me. I'll definitely enter that into my repertoire.

BTW, there is a biological point to be made for moderation. It's called hormesis and describes the observation that many so-called poisons have benefits at low to very low consumption levels. These levels may be different for different people.
