Today the thing I'm choosing to be overspecifically annoyed by is people who are obsessing about benzene in sunscreen but don't wear hazmat gear when fueling their car (gas is full of it). Benzene is pretty benign. Choose a career where you don't breathe it daily and chill out.
It's miniscule quantities on your skin, not a vapor cloud, in a product that by definition you wear out doors. It's the inhalation exposure to benzene that's bad for you and I suspect it's far worse at the gas station.
