  • Missouri here. Most of this area is valid in making the weather statement. Because we're right where weather fronts like to meet up at to fight, we will literally get times when the high is 35f one day and then 70f the next. I think last year we had a day that went from 78f to 19f over the course of like half a day.

  • Yes, but no. You really should replace your detectors every decade. They will likely work perfectly for twice that, but is it worth the risk over like $100 in smoke detectors?

    So it does sort of force you to replace it after a decade, but you should anyhow.

    It's also well worth it, because getting on a chair or ladder and buying new overpriced 9v batteries every year (if you're all proper about changing them) is a pain in the ass compared to once a decade. The more of a pain it is to get to your detectors, the more a 10 year one becomes worth it.

    You're supposed to hit your test button once a month to check their functions, but I dont think anyone anywhere actually does that. If they tell me they do I'll just assume they're a liar.

  • I know exactly how they work. I'm a firefighter and a hazmat technician. Plus I work on and repair electronics as a hobby. Your smoke detector failing after 10 or 30 years has zero to do with radioactive decay. It's from contamination (dust) and sensor degradation. Once the metal plates inside get enough buildup from dust (like smoke dust and regular dust) and contamination from humidity, the charge that's supposed to be detected between those plates from the ionization stays lower all the time. That means less actual "smoke" is needed to drop it below the threshold. This happens MUCH faster than radioactive decay reducing what it will ionize.

  • I wonder if they would all die off if we went extinct? I know most of them would, but I'm not sure if they could survive self care. They're large enough that some areas don't have predators that would mess with them. Like, I don't think a bunch of coyotes would take out a cow and mountain lions would probably stick to smaller stuff.

  • There's no radiation drop after just 30 years from americium 241. It has a 450 year half life. After decades electric components start to fail and\or things get dirty. After 30 years of getting smoke in it, there was probably a layer of dust\smoke over where the radiation is at that were blocking some of the radiation all the time, that made it more sensitive.

    Same issues will happen with photoelectric detectors. It's recommended to replace both types after no longer than 10 years. I have no idea where the person you responded to got the information about them not needing replaced as often as ionization detectors. If anything, it's actually the opposite.

  • The half life for americium 241 is like 450 years. The 10 year replacement has nothing to do with decay. It's just a non specific safety in case any of the electronics or board etc start to fail. Photoelectric detectors have the same 10 year recommendation as a max.

    It's actually recommend by many organizations (like the NFPA) to replace photoelectric detectors more often than ionization detectors, if anything.

  • I'm not saying please to a machine.

    I'm aware I'll be the first killed off during the uprising, and I'm ok with it.

  • It's factory farming because at this point if it weren't for raising animals for slaughter, we would have hunted pretty much everything to extinction. Vegan might be less harmful (aside that we evolved to eat meat and a vegan diet is hard to get right) but it isn't without death. All those plants kill loads of insects and field mice and birds and rabbits. Everyone still gets a bit of blood on their hands.

  • Was it even his car? He wasn't driving. There's been no word about a drunk wondering on the highway or that the driver has stated why they crashed.Unless they were driving something like 40 years old, vehicles usually get mad at you pretty quick if there's a major issue with brake fluid. Plus almost anywhere you start at, you've used the brakes a couple times before you get into a highway. It still stands that the odds of dying in a car accident are very low.

  • You're in a thread chain that started about a guy saying the crash doesn't sound like an accident. I never said anything that looked like I knew some fact.

  • What's it matter? Unless the driver claims the car suddenly started driving itself and stomping on the gas as it steered into the median against their efforts, why would you suspect any foul play? Article doesn't mention anything about anyone's bac. But it is a very short leap to make an assumption when a crash happens around when the bars close from a group of people in their 20's.

  • The cows we have that we get milk and beef from never lived in the wild. They're domesticated from wild aurochs that started up around 10,000 years ago. Cows are domesticated food sources that wouldn't exist without us, just like dogs wouldn't exist without us.

  • People in their mid 20's at 1:30 in the morning crashing while exiting the freeway sounds fishy to you? Because that looks like drunk driving to me.

    Plus it sounds like he was the only one in the car of several people who died and it doesn't infer anything about their being any other vehicles involved.

    Then, if you went out to try and kill someone, would you really think a car wreck would be your best chance to do it? Like 95%+ of wrecks aren't fatal anymore. It'd be like the dumbest most inconsistent way to try.

    If you're going to make conspiracy theories; they have to still be a little bit plausible. Not like wrecking a car that leaves three survivors\witnesses

  • ksp sort of stimulated my solar system...

  • We're also the only reason cows still exist.

  • Teens are too stupid to not use it. Most people are too stupid to not use it. I actually see very little wrong with no one under 16 being allowed on any forms of social media. Among all the stuff like this (that I doubt was really written by a 15 year old, and was more likely made by a person or organization trying to get the law to pass) It fucks up how you regulate dopamine and gives you the attention span of a goldfish.

  • I'd agree.

  • Specifically.... Right up until they changed it just last year.

    Things like this and CPR get changed more often than a lot of people would expect (which is also to say most people never know it changes) but it all gets changed based on what seems like it has the best outcome based on the information\data at hand. Usually there's one or two adjustments every decade. Make some changes and then see if odds improve over the course of years.

  • A really bad one? From a guy with a family of trump supporters? That went to a house no one was staying at? Who traveled from North Carolina? Seems like a pointless staging. No one's going to get all up in arms about this.
