Isn’t it funny that when the plane lands, the little ‘ding’ goes off, and everyone stands up. I mean, where are they going? Even in the first row, the doors still take a few minutes to open.
It’s like a Pavlov’s reaction to the ding. Standing up right after the ding doesn’t serve the purpose to stretch your legs, because you are still in your row. Standing isn’t comfortable at that point because of the electronics overhead. And it’s not like you can run down the aisle to get off the plane because everyone is stuck in the same place.
So the ding goes off, and everyone stands up.
It happens without fail on every flight I have ever been on. Watch for it on your next flight.
