I hate to even respond to this, but...

: Sure..that's correct...you'll likely notice that I didn't mention
: anything about endurance at these altitudes, yes?...ever hear of
: the expression of RTFQ?, a variation on that applies here...

Your original post:

"And don't expect to be able to tell the difference either. I flew
some pressurized but mostly unpressurized aircraft for over 25
years and I defy anyone to tell the difference between sealevel
and 15,000 as long as they're not physically working, are in
average physical shape, cannot see outside the aircraft and have
no instruments...so this particular 'coach experience' claim is
just hype..."

You said nothing about endurance. Simply that it's impossible for normal
people who aren't working hard and cannot see outside to determine that cabin altitude
is at 15k feet. Had you said short periods of time, I would agree with you. In the
context of the original post (i.e. travel on commercial airlines), that is most
decidedly NOT the case. Multiple hours of travel are the norm and would most
certainly cause impairment and potentially other health problems.
