I love the satire. (Did I really write "regret breathing air" before editing or something?) Oxygen is an amazingly energy rich fuel and is super abundant for us. The oxygenation of earth was one of the key steps, and it might be a "hard step" for other civilizations. Of course oxidation causes a lot of damage and byproducts, and is one of the causes of our aging and death. But without it, well... I was primarily referring to particulate matter suspended within the air we breathe. High PPM / particulate measurably reduces lifespan in several population studies, and it also produces noticeable pulmonary and cardiac disease states. Polluted air is bad.
