If you don't understand risk mitigation, or think it's someone else's job - even when, in the case of turbulence the professionals are telling you there is absolutely nothing they can do about it - then eventually you're just going to end up getting injured or killed by something that could be avoided.
Yes, death by turbulence is rare, but there are dozens of serious injuries a year caused by turbulence in US air space alone. Hundreds a year, globally. We're not talking about a small graze or cut, we're talking head injuries, broken bones, life changing injuries. Costs US airlines half a billion dollars a year dealing with it in terms of payouts and maintenance costs. Why you think that doesn't apply to you is a strange take to me, but you do you.
