  • Yes, there’s always going to be outliers, that’s how statistics work. That LD50 is 192mg/kg just means that 50% will have died by that point. Some individuals can survive beyond that point, while 50% couldn’t.

    I’m not saying that 50% of the population will be honky dory a-ok after surviving, what killed the first half. Just that it’s not unlikely that you could survive consuming 18l of red bull over the course of 10h23m. You’d probably still be pretty fucked up, but surviving is a subset of being fucked up, not the other way around.



  • One thing is how you’d feel, another is survivability. https://en.wikipedia.org/wiki/Caffeine states that LD50 for oral caffeine ingestion in rats is 192ppm, and only estimates the value for humans. Wikipedia doesn’t exactly state it but it’s safe to assume that the surviving 50% of rats will definitely not have had a good time though.

    But “36 red bulls” is how much? I can buy red bull in 0.25l and 0.5l cans in local stores, what is available in the US in unknown to me, so I’ll assume equivalent can sizes. So between 9l and 18l of red bull over about 11hrs. IDK that sounds like a lot of fluid no matter what. Maybe the electrolytes in the red bull will prevent water intoxication, but he’d definitely have had to pee a lot. Perhaps his kidneys would have a hard time following along with the excess electrolytes, but enough to become hypertonic?

    Anyway a liter of red bull contains 320mg of caffeine, and thus 9l is 2.88g and 18l is 5.76g. Assuming a 100kg human body that’s 28.8-57.6ppm spread out over 11hrs.

    Had the caffeine been ingested all at once, then he’d at worst have hit 30% of LD50. But given that the subject probably didn’t ingest 18l of fluid instantly, because then the story would include that in the title, the consumption was spread out. Elimination half-life for caffeine is 3-7hrs, meaning that the initial caffeine could be reduced to 1/8 by the end.

    I don’t have the time to do the integral equations, but my best bet is that our subject plausibly could survive, but his kidneys, penis and psychiatric state could do with a check up.




  • Whenever this comes up I like to add:

    • Don’t get a gun in some obscure caliber. Get a pistol in 9mm or a riffle in 223 (even better get a 5.56x45 NATO) or 308 win, that way ammo will be cheaper and you can better afford training with it. Shooting a few hundred rounds is not really enough. You’ll need to train regularly.
    • Learn how to maintain your gun. As in how to clean it, what parts need lubrication, adjusting the sights, etc.
    • Speaking as an electronic engineer, get passive ear protection. Active noise cancelling is cool and all, but what about when the batteries run out and you have no protection? Or what the electronics fail? Protect your ears, but when you can get +100 rounds of ammo for the price difference, then I would prioritize the ammo budget.




  • Well, here in Denmark you can get a NemKey device. But that’s only given to old people in care homes.

    Negative, you can get a device if you want to. Even if you already have an active MitID app.

    In other words, here in Denmark the expectation is that you have a smartphone. Loads of services are now smartphone dependent, like taking public transport (tickets and check-in cards are slowly being phased out).

    Again here you can use an NFC card, but the company behind the common app system really rather you didn’t. So much so that they’ve occasionally taken out half the card readers on the platforms, by putting an advert for the app on them.

    Please don’t be like Denmark. This sucks. Rooting your phone, to get rid of privacy invading bloatware, makes your phone insecure, and you can’t use it for money transfers or ID verification.

    I’m trying not to go off on a rant here, but please don’t be like Denmark.
