Who is this guy? I'm not a scientist so I don't know the measurements he was using nor do I know if his info is correct. I question everything. I'd have to do my own research. Did Youtube really remove this? What a bunch of simps. They truly perceived this could influence people(?), give me a fucking break.
It’s not a sound scientific argument because most of the air you breathe in comes from outside the mask. To get an reasonable measure you could probably assume the volume of the air between the mask and your face is mostly CO2 from your previous exhale and calculate based on the volume of a typical breath combined with that.
Masks absolutely do affect your ability to breathe normally but it’s not as cartoonish as this video implies.
I’m fine with it as propaganda though.
