Not knowing the difference between carbon monoxide and carbon dioxide is the not knowing the difference between death and life. 🙍🏼‍♂️☠

Humans create both when they burn calories in their bodies. Carbon dioxide is the normal byproduct but any burning process has some incomplete combustion creating carbon monoxide including human cells.

Carbon monoxide is very poisonous to muscles including the heart so red blood cells have a strong affinity to it to purge muscles of it. But excessive carbon monoxide in red blood cells reduces the ability of them to also carry oxygen, which leads to suffocation.
