Asbestos has to be in a “friable” form for it to be bad. The particles are so small they can get into deep your lungs. I actually was at a landfill expansion project where a backhoe digging down through the trash hit some bags labeled asbestos. I’m glad it was raining. Also worked in a building with asbestos in the floor tiles. Fine when not disturbed, but anytime they had to remove them it was a production. https://…

In high school I helped a friend rip up the floor tiles in his basement which were probably from the 50s. Years later I realized I could have been exposed to asbestos, is there any way to know whether asbestos would have been in the particular tiles I was ripping up?

I don't have much to add, but felt I should respond.

I feel like the risk is probably less than you think (the facilities people I worked with thought it was overkill for the tiles with a small % of asbestos). but its not zero. As someone who might have been exposed (was in a vacinity), its hard because you can never really know. Also there might have been other instances where exposure might have happened and you don't know (my high school was rebuilt recently because it wasn't 'up to code" when I was going there.

Sorry to ask, but did you have a source for this?

Thank you for this. This guide mentions that it breaks down when exposed to chlorinated water and UV light -- NOT that sunscreen breaks down in storage over time, which is what I was personally concerned about.

My husband was diagnosed with MULTIPLE SCLEROSIS five years ago. It’s very difficult for me to get him on board with major changes to his diet. We eat organic, non-GMO at home but his mom constantly gives us donuts, bagels, etc. I feel so lucky and happy i found World Herbsclinic on the internet. My husband only used their MS HERBAL FORMULA for three months and He was fully recovered. I believe this will be of great help to all MS patients across the world. World Herbsclinc MS formula will reverse your condition, So go for it.

> Medical doctors are no more trained to digest scientific evidence It's about understanding and processing this evidence in the broader context of their medical training. You're trying to generalize the results of a study with many shortcomings to say everyone may be better off dealing with increasing their odds of developing malignant melanoma and dealing with its associated mortality risks. My issues with using th…

> Why not just tell people to supplement vitamin D instead? One very consistent pattern with vitamin D research is that association studies will find a major relationship between serum vitamin D and some health outcome.[1] But an RCT using vitamin D supplementation will find no effect.[2] That strongly suggests that serum vitamin D, at least as we measure it, is merely proxying for something else. The map is not the…

The only reasonable conclusion you can draw from the two studies linked is that vitamin D supplementation to increase serum levels does not significantly prevent CVD. I could just as easily hypothesize that the physical activity required to go outside both increases serum vitamin D and lowers CVD risk.

Just to be clear, I agree with your thought that sun exposure probably carries benefits beyond an increase in serum vitamin D based on anecdotal experience... I supplement vitamin D rigorously, but being in the sun just makes me feel better

I can't seem to find the article I saw a couple months ago. Here's one on room temperature storage for 1 year. This accelerates if left in a hot car or similar environment.

Not if they're all getting a key component from the same supplier. Every niche brand and even someone like CVS isn't going to run it's own chemical refineries for each ingredient in the sunscreen. They're going to use a relatively small group of suppliers. It only takes one of them selling to dozens of manufacturers to taint both mainstream and obscure brands.

QA can be a big differentiator between competing companies that share upstream suppliers. It could be that one sunscreen maker is testing for crap/contaminated precursors and another isn't.

Good point. The difference between quality products sometimes just comes down to specified mechanical tolerances and purity levels of chemicals/ingredients. Though price usually increases much faster than quality at higher levels. Going from 95% to 97% pure might cost $X, but 97% to 99% will be $X * 5.

You make a strong argument for the FDA to get its own fleet of aircraft carriers and probably ground support as well. I bet they'd have many fewer enforcement issues. Then again the optics of the FDA sending a nuke to a company that is non-compliant in it's handling of medical grade radioactive isotopes might be a little bad.

We have serious problems with pharmaceutical pricing, access, and regulation in the United States. Let's not pretend that we have saturated the costs of all necessary pharmaceutical regulation, nor that all of our aircraft carriers are necessary. Here's a list of words to google next to "FDA" as a search term if you want to know where some of the deficiencies lie: Sackler Epi-pen Insulin Shkreli Kickbacks Vioxx Lobby…

Absolutely, agreed.

Should I conclude anything from the fact that almost all of the products with high benzene contents are sprays instead of lotions?

When you look at the list of products where they couldn't detect benzene there are sprays and lotions on it and it doesn't seem to make much of a difference:
