This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

actually i think the body has receptors for CO2? not for CO though. like CO2-rich air outright smells sour.

Fun Fact - Your body cannot sense when air doesn't contain enough oxygen to keep you alive. However it can sense when there is too much CO2 and causes you to panic.
