What really bakes my noodle is that our lungs are more meant to expel CO2 than inhale O2. I even had my great doctor talking about my heart slamming because I was low on blood, therefore O2. I never argue with docs, but we don't have oxygen sensors, only "holy shit that's too much carbon dioxide!" sensors.

    I mean biologically speaking, having to breath and eat from the same hole is pretty annoying. We need to bioengineer humanity away from this entire active respiratory system nonsense.
