One of the things travel reminds me of is how many people spend such an incredible amount of their time in poorly ventilated spaces. Do you have any idea how much better you'll feel and think and sleep if you live in rooms with CO2 400-600ppm instead of 800-3000ppm? Also, have you ever tracked the CO2 in your car? You're probably doing something incredibly dangerous with remarkably reduced cognitive capacity.

@sus Early on when we learned that CO2 levels correlate nicely with COVID risk, I had unintentionally left my CO2 meter powered on when I was driving home from work, and I didn't make it 5 miles when it started screaming at me and I realized how bad it was to have my ventilation system set to recycle instead of letting in fresh air. The difference was shocking.

@sus I remember when I was younger and my Dad had a pretty new car and the AC system had a 'recirculate' button on it. It was great for times when you wanted to keep exhaust out of the car, or just keep the air cooler without the AC working so hard. At some point, we started to get unusually tired, and we eventually figured out that it was the recirc. Sealing on a car HAS to be good for all sorts of reasons, but really, it's probably too good most of the time. Draw air in through the vents at all times if you can.
