How do you even cross a road with that approach to risk?
The risk mitigation technique for dealing with severe turbulence which frequently injures people, and only rarely kills people (thankfully), is to keep your seatbelt loosely fastened, and get out of your seat only when you need to.
The fact this is considered absurd by some replies here is a fascinating insight, TBH.
I fly a lot on routes over the tropics and have experienced serious turbulence multiple times. There's no way I will be wandering around the cabin unnecessarily.
I always thought there were relatively few people with this mentality, that a simple and trivial precaution is totally unacceptable and infringes on their entire life. Then COVID hit and we all saw just how many people would not even lift a pinky finger to help mitigate risk for themselves and others. I don't understand it, either. Do y'all just go out and jump off cliffs every day because you're free to do it?
When crossing a road one has more input to judge the risk by looking in both directions, seeing potentially oncoming cars and estimating their speed.
In the plane you have no way as a passenger to know when it's more or less likely that turbulences are flown through or how heavy they would be.
