The 2019–20 coronavirus pandemic brought on social distancing suggestions.
     
“If you can smell their fart, you’re not far enough apart” is a message that was posted on a board of the Lebanon (ME) Fire-EMS Department, Station 2, on March 19, 2020. “If you can smell their fart You’re not far enough apart—Lebanon, ME Fire EMS” was posted on Twitter by Cindy Smith on March 19, 2020.

Shared on Reddit by jimmyb207, that’s just the kind of sign that you drive past and say “never really thought of that but they’re damn right”. For the record, there’s no scientific data that supports the theory that if you can smell someone’s fart, you’re not far enough apart. But sometimes we don’t need science to know that if you catch a smell, better run like hell.
