Thank you Eric.

I didn't say I felt fine, I said I can't tell the difference.
Above about 20,000 ft or so, I can tell the difference. I start to get a
headache and my ears tingle.
In addition, even at lower altitudes, if I divert blood from my brain,
(how
does he do that, you ask?) by eating
a sandwich or the like, I have to get on O2 immediately. I can really
tell
the difference.

No Bill, I am not a Sherpa and I can't quarrel with the acclimatization
point. I can only tell you what I experience.
There is no such thing as too much education and/or knowledge, so I can't
disagree with you there.

I haven't gone over 26,000 ft so my descriptions are only valid - for me -
up to that altitude.

I'm not really disagreeing with what you say, only with the thought that
regulations are required to make
it work. All the regulations in the world have not stopped stall-spin
accidents. How about we work on
that one?

Allan, we absolute agree about additional regulation.

My point is that we should use good oxygen systems, a pulse oxymeter and
read all the important literature.
