Years ago I watched a documentary about garlic production in China; in short prisoners peel garlic by hand (till their finger nails fall off... Then they have to use teeth/feet) and it was (allegedly) then shipped across the world (including US) I have thought about this every time I've peeled garlic since and it won't stop :/
It was Rotten - Season 1 episode 3 "Garlic Breath", on Netflix, if you also want to feel sad while cooking
