  21. -I wasn't suggesting enriched oxygen: A 10 psi, 20% oxygen atmosphere
  22. -should be perfectly acceptable. That's less oxygen than at sea level,
  23. -but certainly enough to support people (even physically active people).
  24. -Since there are cities with this sort of partial pressure of oxygen,
  25. -and people, in fact, go there to be physically active (ski), I'd say
  26. -there is considerable evidence that this isn't a health problem.

  28. Apparently anything significantly below 3 psi partial pressure of oxygen
  29. is a potential health risk, unless you have many generations of ancestors
  30. who lived in the mountains. The body undergoes various changes to adapt to
  31. low oxygen content, but some of these changes have undesirable side effects.
  32. I'll try to find that Scientific American article again and post a summary.
