There was a row of chairs (touching each other) at work that are purposefully very heavy. I wanted to look under the chairs, so I was lifting them one at a time. The last one was a corner chair and a lot heavier. I stuck my head behind the last chair to look under it, dropped it, and caught my jaw. It hurt like fuck but fortunately didn’t do any actual damage.
That’s not great but the guy above you reckons you’d die quickly, due to not having enough air.
