The problem is that n-hexane is a potent neurotoxin, and all these people have been exposed. Their hands shake uncontrollably. Most of them can't even pick up a glass. I talk to people whose joints in their hands have disintegrated from working on the line, doing the same motion hundreds and hundreds of thousands of times. It's like carpal tunnel on a scale we can scarcely imagine.
This again proves my point that they see workers as commodities and not living people.
