Oxygen Bars

[sweet angel]

there should be helium bars so we can walk around sounding like munchkins

Now that would be funny.

Isn't the oxygen in high-altitude places lower than the oxygen in lower altitude places -- or is it something else?

My point being, maybe someone who lives in an area with lower oxygen would get used to it and function normally. Of course, if it's not oxygen that's lacking in higher altitudes, that point is moot.
