Correct... A "cup" is a unit of measure... A glass is just an arbitrarily
sized container...

I remember bitching about my expresso maker when it claimed that it made 6
cups... It made 2 at best and I'm not even sure they were a full 8
ounces...

Just about every coffee maker I can recall, has it's graduations for CUPS
being 5oz. (i.e., 12 cup variety holds 60 oz of water).

Thanks, interesting. Our local know-it-all is spouting BS again, as can
be easily found out with a little googling and wikipediing (that a word
yet?).

Any suggestions on preflight preparations that have worked for
others ? No coffee before the flight ? No liquids xxx hours before
leaving etc. etc. Sort of like preparing for an operations.

Dehydration gives no warning and can seriously degrade your pilot
skills just when you need them most. Drink normally and use piddle
packs to extend your range if you really don't want to land. Some
glider pilots make their own with freezer bags and the gel that is
found in some diapers. There are also products made to accommodate
the female anatomy.
On the other hand, having a desperate urge to pee and no place to
do it can also degrade your performance. Always have a plan. On my
little x-country flights, I always pack a bottle of water. It is
always nice to have the water should I happen to get thirsty, but In
a pinch that bottle could be very useful!

The QED of that is to look at what goes on with patients who are given

the collection bags would not get as full at night.

I only know what the medical textbooks say. Renal activity, like most
other types of body activity, does decline during the night. That's
why most people can go all night without getting up to urinate, unless
they drink a substantial amount of fluid just before going to sleep.

It's interesting how people pick and choose their sources and adjust
their standards for reliability as a function of how much these agree
with those sources.

Mxsmanic,

If you were ever under the impression you had established yourself here
as a source, any kind, let alone a trusted one, you're even more
delusional than I thought. What would you have done to even try being
taken seriously?

But again, you're finding a nice rationalization to take away the blame
from yourself.

You're not reading enough of the textbook. Understanding more about
human physiology and why reduced kidney function is driven by a lesser
metabloic challenge, rather than it being dark outside, would have
prevented you from making a misleading statement.

Night = sleep = diminished metabolic challenge = reduced renal
activity

There's nothing misleading about that, unless your patients are
vampires.

Sigh.

It is not its pH that makes urine corrosive, but the dissolved salts
that become reactive. That's why cars that are close to the oceans rust
more quickly than do those in rainy inland locations.

Sooner or later you may get something right. Let me rephrase that.
Sooner or later you may apply a known fact correctly to the situation
being discussed. That urine is more or less neutral, or even more
importantly has little buffering capacity, is true, but that fact is
not relevant to the topic.

with a bit of urea, and a neutral pH.
