If someone next to me farts and I feel the vibration on the bench, should I be alarmed?!?

She had nachos that day.If someone next to me farts and I feel the vibration on the bench, should I be alarmed?!?
Run like hell its not the vibrations you have to worry about its whats coming next!
why? Are her farts a bio-hazard?
Gas is often caused by the inability to properly digest foods, so from that respect there might be some concern.
I would think SHE should be alarmed.
lol, nah, okay think of this. A fart is an "explosion" of air comming out of the rear end. Also think of this, When you blow on water or a sheet, they move right-ripples in the sheet and ripples in the water, same thing with a fart, when air hits it causes movement. I'd say that she shouldn't eat nachos unless she plans on getting bad gas. Or give her some Beano.
Yes if u are close enough to feel the rumble then u are close enough to breath the noxious fumes. Beware.
