They accumulate gunk that was present in the cold water supply.
Yes, but water coming from the cold water tap has spent less time sitting in that accumulated stuff.

In the past it was common knowledge not to. It's of much more uncertainty as house plumbing has changed.
That's because it is primarily a historical artifact[0]. Most modern plumbing heats water on-demand, which pretty much entirely avoids the risk of storage tank contamination or Legionella. [0]: https://www.youtube.com/watch?v=HfHgUu_8KgA

Are there? It seems like plastics are shaping up to be the modern day lead.
Lead roofing tends to get recycled into bullets in time of war, but those roofs that don't, are typically there forever (400+ years) and never leak. Some plastics are UV resistant due to additives but even copper struggles to compete with lead as a roofing material. You only need to look back to the 1970s to find PEX water piping and the disaster/flooding it can cause due to age.
That's interesting - I've read that there are a lot of castles and stately houses whose demise started from the owners selling off the lead roof, but I never understood why it would be so valuable that you'd destroy the building for it. Is that why?
Studies like these always make me wonder what the equivalent of this today. Microplastics? Carbon? What else?

Don't lick your boards, wash your hands before you eat, and if you're really concerned, wear gloves while handling solder wire. The smoke from soldering isn't lead - a soldering tip is (if it's not literally glowing into the yellows) far, far too cold to vaporize any lead from solder - you need to be 1500+C for it to start being a problem, and you're not soldering that high. It's rosin smoke, and if you're in doubt,…
Also, afaik, there's no reason for hobbyists to not always use lead-free solder. But of course that doesn't mean something you're taking apart used lead free.

Wow. How does one develop an iron deficiency in America? Bread and breakfast cereals are fortified with it and it's in multivitamins, eggs, pasta, most meats, and even some chocolate. I get spinach and peas aren't for everyone, but how does one end up with a deficiency in iron when it's added to the trashiest of food? (We shit on it now, but maybe this is why the "food pyramid" was shaped so contrary to current sensi…
Women literally lose iron every few weeks, and many plants contain anti nutrients (phytic acid) that bind to metals, reducing their absorption, such as beans. In general though, I wouldn't place the blame on plants, but on the low quality, highly processed diet the average person consumes. I have ADHD, and I've noticed symptoms of low iron whenever I stray from my very low carb diet: restless legs, low energy, ADHD s…
Heh, great point.
> and many plants contain anti nutrients (phytic acid) that bind to metals, reducing their absorption, such as beans.
Also a good point, and will come back to it--
> I have ADHD, and I've noticed symptoms of low iron whenever I stray from my very low carb diet: restless legs, low energy, ADHD symptoms getting worse. Note that iron is a necessary component for the synthesis of dopamine.
Right. You make an excellent test candidate then-- is this speculative or have you actually tested your iron levels during those times?
I'd again question whether what you're feeling there might actually be a potassium/magnesium problem. You say "symptoms of low iron," and that's true in fact-- but it may only be low because you're consuming but not absorbing enough of it. I doubt you have much of an appetite.
Assuming you aren't bleeding out from gunshot trauma or menses, the next time you're feeling symptoms of what you're attributing to low iron, try eating a daily banana (or take prenatal vitamins or something).

Why are there so many loopholes in every single US law? Everytime there’s a major health issue or anything extremely anti consumer it’s because of a loophole in the formulation of a US law. Are US lawmakers that bad? Or is it judges who interpret laws literally instead of using the intent?
People shit on California's Proposition 65, but the notices at Fry's made me aware of the lead content of solder, and the ones at Michael's highlighted the lead in Christmas decorations, lights, and fake trees/garland. I went most of my life ignorant of all of this. But banning stuff outright seems like it would be counterproductive to either industry (banning soldering would be disruptive) or public image ("Liberals…

This is a common predicament. A piece of information that, if it was made public, would be immensely useful in countless ways for the management of our society, But it might also be exploited by bad people. So it is made private. And the icing on the cake. We say "it's private because privacy is intrinsically good and a basic human right ". Not, "It's private because we fear bad people".
>would be immensely useful in countless ways for the management of our society, Such as? Now, maybe if one person had an IQ of 80 and the other contender had an IQ of 105 it seems like it could be useful in some particular fields. But for the most part you'll run into the "I'm 200 times smarter than you because my IQ is 102 and yours is 101". And there is no icing on the cake. Privacy is a multipolar topic and there…
If we were looking for smart people for a role in whatever. There's another.
If we were rating schools. There's a third.
Gee, my imagination is feeling so stretched.
