I wanted to argue with you about this, as I have experience working as a construction site laborer, and then I thought back to the time I had to spend a night on-site because a huge beam fell off a wood pile and pinned my leg in the dirt and other fallen lumber, and everyone else had gone home and no one could hear me yelling.

I wasn't seriously injured, but ninety nine out of 100 times someone in that position would be.
