Grift. Same for blood boys. The meritocracy is just a lie, the rich are dumb as shit like everyone else.

Something I learned recently on another topic: The human body is 67% oxygen by atomic mass.

You don't breath poison. You are poison.

I have no serious knowledge about it, but for the thermic aspect I can't imagine it working in any way.

Your body will try its best to keep its core temperature constant. So you won't really cool your cells down.
In this process it will burn even more fuel to produce heat, so quite the opposide they want to archive.
