A lot of people don't know how to determine if their body is telling them it's
dehydrated. A l-o-n-g time ago a doctor told me to note the color of one's
pee -- if it's yellow you're dehydrated.

Conversely, don't drink too much water as it can upset the body's sodium
balance and cause cell expansion and rupture. The local news recently
reported a bicyclist in a marathon drank way too much water and died because
the brain couldn't expand any further in that person's skull. Eerie.

I felt the need to expand upon this. First, please note I'm NOT qualified to
dispense any medical information. Second, my recollection of that recent news
article was that 1.5 liters of water per 6 hours is the MAXIMUM one should
intake. The article was NOT clear if that meant "water" from all sources (i.e.,
moisture content of food one eats or just "plain" water that one drinks). If
in doubt, consult a qualified medical authority.

The point about the color of one's pee is valid dehydration determination
and was again mentioned to me by a cousin who piloted the EF-111A planes during
Operation Desert Storm. My cousin also mentioned that as little as 10%
dehydration dramatically affects (pilot) response time (flying jet aircraft)
brain and muscle activity, so this IS something to keep in mind while "piloting"
one's scopes under adverse weather conditions.
