I know this video seems scary, but all of these things are actually safe to eat. Just unappetizing perhaps for some. I will say that the correlation in the video of PG to Antifreeze is completely wrong. Vodka is a good anti-freeze as well. Vodka is good.

When you really think about all the things we eat and what happens after we eat, the human body is pretty gross in general. I guess that's why doctors and nurses make good money. Some of us couldn't hang with all the nasty stuff that people have going on with their bodies.
