Ha! this is hilarious. I love the picture of the guy sleeping with his head sticking out the door!
What's he supposed to do in the event of rain, snow, or frigid temperatures? ha!
Or what about people with second-story bedrooms, but no balcony? I suppose a person could elevate their bed so they were sleeping up by the ceiling. That way the heavier CO2 would settle down by the floor and they would be able to pass the night in safety.
I've never actually heard this before - about plants in the bedroom supposedly being dangerous. And here I was planning to put some lighted shelves loaded with orchids in my bedroom!
