  • First of all: Where in your system was the sample taken? At the well? At a tank? At a faucet?

    The answer to this question is important for the next steps.

    Be aware that high lead content can also be an issue for plant watering and even showering.

    If the sample has been taken at a endpoint (faucet) I would try to get another sample at the well directly. If you are “lucky” the acidity of the water is the reason lead is brought into your system from a section of your transport system. In that case replacing the transport layer (basically: Get new pipes) is the best approach - while it’s not cheap it is also not as expensive as filtering (or dealing with the health issues from lead, especially in the US).

    If the well shows the same values you are screwed. There are basically two scenarios then: Your well installation itself is the problem - this is in theory “fixable” but expensive, but you might accidentally even poisoning your neighbours then. (The way to find out if it’s your installation is either with specialised equipment or, for some confirmation, get a sample from a neighbour who ideally life upstream from you)

    If it’s not your well installation then it’s the well itself…and then you really really need a more extensive analysis: Lead in a ground water deposit is somewhat rare and often a indication something else is problematic - both because geologically lead is often next to other nasties, but also because human caused pollution with lead often goes with the real nasty stuff like arsenic,etc. And you really would want to find these. Then shit sadly becomes really expensive.


  • Nope,it hasn’t. If your glasses are fogging up in sync with your respiration rate or within a very short timeframe your mask is not sealing. Period. The only difference is when you have either have a valve mask, work with a face shield or similar things or in confined spaces - it’s basically impossible to fog up your glasses with a correctly positioned mask as the filter medium does work as a diffuser. If your mask does fog up suddenly despite a confirmed fit it usually is a warning sign for a breakdown of the filter medium.

    (And believe me, we tried really hard - as part of a customer contract we tested all major mask manufacturers available in the EU, with a sample size in the 4 digit range, including UV fluid and thermal imaging tests)

    I am fully aware that the equivalent of N95 is often seen as comparable to FFP2, but this is not actually quite correct. The FFP2 has a slightly worse filtration rate and a slightly higher resistance both for inspiration and expiration. Anyway, I intentionally wrote FFP3 as this is the recommended FFP class for Measles while within the NIOSH legislation only a N95 is recommended.



  • The European union never had any intention to be limited to land borders within Europe and explicitly understand themselve as a economic and trade, ethical values and international cooperation based union - which by the way does include far tighter equal defence rules than the NATO accords. This is especially important as Europe is not a well defined geographical area and its borders are somewhat fluid.

    Remember that before Erdogan Türkiye was considered as a possible member, Cyprus is a member, Georgia was on its way to a membership before the current government took a tour to Moscow, etc. The longest single country-to country land border the EU has is the French-Brazil border.

    And Canada has as much of a border to a EU country(but not the EU as Greenland is not part of it) as e.g. Türkiye has it’s European parts. So after all…this is not an issue at all.






  • Healthcare professional here - but not your HPC and you cannot confirm that I am who I am so double check what I write:

    • Get your titers checked and get revaccinationes asap. If you are not vaccinated or are a non-responder talk to your healthcare provider. Isolate until then.

    • Mask up and keep your hands away from mouth, eyes and nose. You will need a properly fitting FFP3/NP95 mask here - measles are far meaner in terms of infectiousness than COVID. Tight fitting means: You have no leaks at the side - if your glasses fog up, if you can feel air going in or out next to your face,etc. it is not working. The usual “duckbill” masks with straps around the ears very very rarely fit properly.

    • Wash your hands and desinfect them properly.

    • Stay the fuck away from babies. Really. Please.



  • Yes and no. Old job was more IT and process related, nowadays I work more in disaster planning , public health policy and process planning in healthcare, spiced up with a bit of medical intelligence.

    Basically hospitals, large companies and government bodies are legally required to have plans for major incidents (from “hey,there has been a train collision, you get 30 severely injured in 20min” to “shit,we lost all power” or “IT outtake”) - we do the planning and training, including life exercises for you. You want to update your healthcare system/the placement of your prehospital resources(ambulances, etc.) as a state or government body? We do that that for you.

    You need to know which hospital in a random African country is the right one for a tourist with a sudden rare disease or your insurance wants to know how safe it is to send on of your staff members someone right into the current emerging disease hotspot? We do that for you.




  • I personally would start with TPU(after PETG) - the different shore grades provide a large usability for a lot of things and it print comparably well once you find the right calibration. Especially with a A1 as you mentioned you have one.

    To be honest I would skip ABS totally in an A1 unless you have an external enclosure with a good filtering and exhaust solution. Be aware of the noxious fumes ABS will produce that have a potential to intoxicate you and are suspected to cause cancer depending on the additives. (Among others ABS produces hydrogen cyanide when printed - which is often better known under it’s former German brand name: Zyklon B…)

    ASA nowadays provides a far less problematic (but not unproblematic) solution and while it’s a little bit more complicated to print it’s still manageable depending on the filament manufacturer. But you will need a temperature stabilised enclosure for both anyway, while ASA is a bit more sensitivitie,it doesn’t really matter that much for me.

    Within ASA I personally found a far larger bandwidth of printability between the manufacturers. The major manufacturers for PLA often suck - especially Bambu Lab ASA is hideous to print. If you are in Europe I cannot recommend the Black Forest Filament ASA enough, their stuff is not comparable to any other ASA I printed. Alternatively material4print. If you need a filament that is available worldwide Filamentum Apollo X is a solid choice, so is Polymaker,but both to a lesser extend.

    In theory PMMA, PCTG and CPE are also worth a consideration, but besides CPE all of them are far more difficult to print.

    BTW: All variants need to be printed very dry, ideally out of a warm dry box.


  • You can easily kill yourself with a water overdose (and it’s actually fairly common),so yes.

    Nutmeg was already mentioned - high doses can easily kill someone, sadly even without hallucinations simply by killing off ones liver and dying an agonizing death a few days later. The same goes for cinnamon, but with a much lower dose.

    There are a few more, but I don’t want to give people too many ideas.

    To make it short: Yes, possible,but it’s mostly a very slow death over multiple days that fucks you up really bad and is a horrible way to go.



  • Tbf, comparing blender and openscad is more like comparing a hammer with a knife.

    FreeCAD would be the more obvious comparison here - and while Openscad has some benefits for more complicated projects it is less than optimal - and sadly FreeCAD still sucks compared to most commercial products,even though it has improved recently due to the ONSEL influence.
