Capitalist dystopia prediction: future office buildings will have "custom" interior air mixtures with decreased CO2, slightly increased oxygen, and, if costs permit, some of the nitrogen replaced with inert gasses like neon, krypton or argon. The end result is that the air is more "energizing" (and healthier too), leading to an subtle positive stimulus associated with being in the office, whereas being outside or at home the stimulus is absent.
@IceWolf it sounds wild considering the atmosphere is *mostly* nitrogen, but life is very complicated, it turns out
@IceWolf Nitrogen is bioactive, and there is some research to show that it is very slightly toxic as a gas. Hypothetically reduction of exposure to it may extend longevity as a result. Research is ongoing.
