Only until we figure out how to transmute it to gold.

We already know how (bombard it with Calcium-48 in a particle accelerator, or stick it in a nuclear reactor), but it’s not cost effective.

Actually, there is a startup that's about to make it cost-effective through blockchain-based crowdsharing:

What is still a safe lead blood value? And is there any merit in "chelation" therapies, as advocated on health websites, like this one, [1]? [1] https://www.livestrong.com/article/199912-what-natural-herbs...

There is merit to chelation therapy as a means of eliminating mercury (and other heavy metals including lead) stored in the body, but many protocols, both alternative and conventional, don't consider the full complexities involved and can be more harmful than beneficial. There are a number of relevant factors including length of exposures (acute or chronic poisoning) and form of metal (organic, inorganic, metallic -…

Hi, thanks, I know it's well-intended, but I can't find Cutler's work on PubMed, so I'm still wondering how legitimate this work is.

Fairly common knowledge. In fact, because Spirulina absorbs heavy metals, it’s important to get Spirulina from clean sources as you may be ingesting Spirulina that already has absorbed heavy metals within it. Be careful.

>Fairly common knowledge So complete nonsense then. Got it.

Please don't respond by degrading the discussion even further, regardless of how right you are.

With an ever expanding world population, possibly on the verge of unsustainable, would a plummeting birth rate necessary be a bad thing? Sure it would mean redesigning how we see the world (the retirement and economic models), but we can either tackle it now or when it's forced upon us.

Well if the only effect was a plummeting birth rate, then maybe it wouldn't be bad, but it's also been testosterone levels that have dropped considerably[1], which according to that site "[decreased testosterone] is often associated with diabetes, abdominal obesity, sexual dysfunction, depression and other adverse conditions." There have also been increases in those who identify as LGBT[2]. Such massive increases in…

Are you sure it couldn't be explained by cultural changes? Perhaps the numbers were always there, but higher cultural tolerance has simply brought more out of the closet? At the very least I would expect that to be a contributing factor.

I remember reading about how the increase in mental illness could just be that we are better at diagnosing and recognizing them (and lazy doctors who would rather just prescribe something for your "depression").

Only in priston engines, and it’s mostly due to the fact that changing the engines, which are currently reliable and in many cases have been for decades, could introduce new issues. It’s a snails pace industry due to safety and reliability concerns for the most part. It’s super annoying because i always want the best new thing to go with a plane, but when you’re in the cockpit, it’s comforting knowing the plane is 80…

Also, most small airports only carry one fuel, i imagine those making new planes don’t get customers excited about planes you cannot take everywhere due to limited availability of fuels. I love/hate flying for all these reasons.

Some engines (such as Rotax) can be run on mogas, available at gas stations. Obviously you then need to transport it to the airport yourself, which isn't always convenient.

Does anyone know of what foods mitigate the accumulation of lead or other heavy metals in the body?

The reason I asked the question was to see if anyone had had medical advice on the subject. My father was a printer in the days when lead type was used. Over a long period of time he accumulated lead within his body.

His doctor advised him to eat beetroot every day. Over a period of several months the amount of lead that had accumulated in his body was reduce to negligible amounts and he never had the problem again. Mind you, he still eats beetroot today and he is in his mid-eighties. He was in his mid-thirties when he started.

I was wondering if others had been advised by their doctors on this subject.

No I'm not sure, nor is anyone. But having 1.4% of boomers and 7.3% of millennials identifying as LGBT is a _massive_ difference. Homosexuality is something that by all indications causes incredible mental anguish by suppressing, and from what we understand doesn't really change over a lifetime. Wouldn't we see a massively large number of older people coming out of the closet? Would it really be surprising if endocrine disruptors could have such a massive impact?

I don’t know man. It was just something I knew from some time ago and there’s no end of google results that talk about this. Not really sure what other source you’re looking for. A research paper? Even those can be nonsense.

> A research paper? Even those can be nonsense. An absense of research papers is far more frequently evidence of nonsense

Not really. All the absence of research papers indicates is that the subject has not been considered to be worth the time or money to do research in the subject.

There is only so much time and only so much money and as a consequence, priorities are made as to what it should be spent on.

Even replication of results is not deemed worthy enough to spend time and money on. We see this often enough where papers detailing the replication of an experiment are simply ignored in the journals for that field. This comes up in discussion in so many different fora across the internet.

If unlimited funds were available for research into all and every subject, there is still the lack of time and researchers available to do all of the research necessary.

So what happens is that whoever has the most influence and the available funds and time gets to dictate what gets done. This means that for other research, it depends on the efforts of those who have a burning interest and motivation to do the study.

I, myself, have a whole series of experiments that I want to undertake. it will have to be by my time and money as it is a subject that I especially want to investigate. But that is still dependent on all the other commitments that I have. I, at least, have a couple of young people who are willing to help with the research when I get it progressing.

The particular area has much hype but no widely available experimental results to back up any claims from either side of the discussion. I am designing the series of experiments to try, as best as I can, to get as detailed results as possible for future possible experiments and direction of research. In my own study, I have found only three other groups around the world that have even looked into the subject with any sort of experimental detail.

Want to feel a bit concerned? Carbon fiber particulate (such as what you get from sawing or sanding it) is as bad as asbestos. We love carbon fiber these days. Most of the time it is sequestered safely away in resin, but it's absurdly simple to free it.

Can you point to a study backing up this claim?

https://www.scientificamerican.com/article/carbon-nanotube-d...

Second link in a search containing solely "carbon fibre asbestos". It's a fairly well known problem. The problems with carbon fibre (and asbestos, for that matter) is not that it's somehow poisonous, but that the particles are so fine and long and strong that they cause problems with your lungs. They can't be absorbed, they can't be expelled; their structure makes them an irritant that can't be removed by the body's natural processes.

Lead is still used all over the place in he USA. Its very concerning. You have to specifically look for lead free versions. Examples: * "fake" christmas decorations (trees, wreaths) often contain lead * Garden hoses almost always contain lead

Most electrical cords have it in them as well. Believe stuff from IKEA doesn't though as it meets EU standards.

Look for "RoHS"[1] on labels and electronics. That governs a list of materials, but I suspect the most common is lead. Among other things, this is the origin of significant usage of lead-free solder, which has led to its own set of issues in electronics (brittle joins, tin whiskers, etc).
