I was homeschooled previously with a small group of other children and we fart in class all the time.
Now I'm in public school for high school and no one is farting. I was very sheltered and public school is like a whole new world for me, so I don't know what the norms are. I've been holding it in but my stomach hurts and it leaks out anyway.
I don't understand how there are so many more people in high school and yet zero farts...
Honestly, if you can't hold your farts until you go to the bathroom without it hurting, you might need to get on a medication or something. It's extremely rude to do that around other people. What would you do on an airplane?
My relative was a stewardess, and she said the ups and downs of many flights a day (domestic, multiple small flights) combined with airline food would give them all gas.
They had a maneuver they called “crop dusting “ whereby they would release their gases during nonchalant walks up and down the aisle.
This helped disperse the fumes rather than leaving them concentrated.
Due to the lower air pressure inside of an airplane when af cruising altittude (comparable to the pressure at around 2500m of altitude, iirc) the gasses in the bowels expand, causing more discomfort. That’s why everyone gets more gassy in a plane, although I can imagine that airplane food and fucked up circadian rythms contribute as well.
