  1. Makes sense we could do that. The intestines are adapted to absorbing things. I suspect we’d need to cheat for it to be effective though. The rectum has way less surface area than the lungs (your lungs have about the same surface area as a tennis court), so we’d need pure O2 or maybe even that liquid breathing setup from the movie The Abyss.

  2. I’ve just seen a vision of the Olympics, 2050, and everyone has giant monkey-butts with plugs that increase oxygen uptake.

    I’m sorry, but I had to share that with you. Science fiction is supposed to *prevent* the future, not predict it.
