A recurring topic of discussion is altitude sickness and treatment.
AMS (acute mountain sickness)
Time and a distinct lack of resources can quickly elevate the
dangers of a medical emergency.  High Altitude Pulmonary Edema (HAPE),
High Altitude Cerebral Edema (HACE), and retinal hemorrhaging
are all problems which can take place in some individuals as low
as 5-8,000 feet.  You can read references, but you have a responsibility
to be in reasonable physical shape, drinking plenty of fluids.
But the important thing to realize is that you have a MARGIN of
safety you are cutting into.
You should consult YOUR physician about YOUR special needs.
Diamox or Previtin should not be taken lightly.
Reactions to other drugs (even aspirin), allergries can differ at
higher elevations.  See a physician.
Another topic where urban thinking can harm you.
Drug treatment is not a substitute for descending.

Gamow bags have been discussed as an expensive measure (perhaps most
useful for high altitude expeditions).  Bottled LO2 is also a possibility.
