Not necessarily a good thing knowing the science - just off the top of my head... Topics I wish I'd never known about - General anaesthesia and low dose - General anaesthesia and the idea you are actually awake but forget. - General anaesthesia stats and possibility of being awake (moreso if you're anxious about not going to sleep - it's happened to me with gas). - Flying and why the plane needs to dive for certain scenarios. - Flying and tolerances for wings during a storm (they're good but still!) or lightning strikes (Faraday cage but...). - Flying and knowing about coffin corner stall limitations/margin for error. - Flying and survival stats if there's actually a serious incident. Probably a load more...!

  I think the parent poster if confusing general anesthesia from sedation [1]. If you got a colonoscopy or your wisdom teeth out, it was probably sedation. If you got major surgery where they cut a big hole in you, that's more likely to be general anesthesia. "Twilight sedation" is pretty spooky from a philosophical perspective. You are somewhat aware of what's happening to you and are experiencing it in the moment. But you are unable to form long term memories of it, so after the procedure, it's like it didn't happen. But there was a point in time where they you that you were was at least somewhat conscious of the procedure. [1]: https://en.wikipedia.org/wiki/Sedation https://en.wikipedia.org/wiki/Sedation

    The other aspect of twilight sedations is: do you feel pain and then lose the conscious memory, but retain the stress reaction's affect on your body? And similarly for anesthesia: even if you don't feel pain, is your body having a stress reaction? Obviously yes to some extent, for the non-neural pathways that are physically insulted during the procedure, but what about for neural pathways?

    When I had my wisdom teeth out, I had a "dream" that I was on a old wooden mine-cart styled roller coaster with wheels that were sparking dramatically against the rails first on the left side, then on the right. (mirroring the teeth removal)

    There’s also the concept of anesthesia awareness [1], which does apply to general anesthesia. [1]: https://en.m.wikipedia.org/wiki/Anesthesia_awareness https://en.m.wikipedia.org/wiki/Anesthesia_awareness

>Flying and survival stats if there's actually a serious incident. This is such a bad contextualization of the risks if you actually know the stats on the matter, since there are ~600 million passengers per year and <600 (as in, fewer than a thousand) fatalities; you have less that one in a million chance to experience a "serious" incident - in fact, I'm pretty sure the definition of a "serious" incident in this context is "an incident that normally results in a large number of fatalities". Which makes your stat above very nearly a tautology. My point is that this is very much an example of where internalizing the stats should make you feel safer, unless you're letting a cognitive bias (like anxiety) prevent you from actually internalizing the real risks.

  I fly because I know the stats. I worry because the stats for survival are low (or worse, you actually survive the impact). It also doesn't help that I live near a major airport and almost on a fortnightly basis we get reports of planes declaring minor emergencies and having to turn around or be diverted. Occasionally it may be bird strike/engine fire.
