Yep, and breathing oxygen is even more lethal. 100% of people who have died breathed oxygen not long before dying. Eating is also lethal. Eating has been noted in almost all people at some point before they died.
Funny about the eating.
The old man tells the waitress waiting on us he wants four eggs, fried hard. She says “Sugar, that will kill you.”
Pop says “Sugar, starvation will kill you faster, get my eggs.”
