Yeah, I had to look up the reference to the Ironman and did find at that
URL, as was the intake guesstimates for a runner, but the rest of what I
wrote was actually drawn from several sources (as I said) and combined
in my own head over the past couple of years.  The most recent, which
was why it was more fresh in my mind, was an "article" I heard on CBC's
As It Happens the other night (or was it "This Morning Tonight"? --
which is why I didn't mention it, as most of you likely could not have
heard it, and I don't remember exactly what program or day to mention! :-)

Yeah, like an over-extended stay in a sauna, or working too hard in the
mid-day sun in the Tropics ("Only mad dogs and English men go out in the
mid day sun!"), or working in a blast furnace facility, or as a glass
blower or blacksmith without A/C in the summer, etc....

Even me sweating away in my office-become-sauna today I don't need
anywhere near 32oz/hr to prevent heat stroke!  I don't know how active
the rest of you are, but if you're reading this list then I'll bet
you're more likely to be sedentary than not.
