Yeah, the more I look into this, the more complicated it seems. I didn't realize the balance of the gases was so important, I thought I just needed more oxygen. A CO2 scrubber would seem to have the same issue, right?

I agree I could just increase ventilation, and that's what I'm doing now. But I recently realized that many extremely-productive people are getting their productivity from using stimulants like caffeine, and so now I'm wondering what other things I could modify in my life to be more productive. I'm just trying to optimize everything.

The CO2 scrubber, would do the trick, I was thinking about hypocapnia but that probably isn't affected by inhaled CO2 but the rate at which you purge metabolic CO2. So not sure there is a downside to pushing it too far the other direction the way there is with O2. But I think a real scrubber based solution would be cost prohibitive and perhaps finicky and noisy compared to a ventilation based solution that would do 95% of the job.

Got it, thank you for your opinion.
