Be sure to not take strengthlevel.com too seriously.

The skill set required to reach leadership positions does not necessarily match the skill set of a good leader.

Very commendable approach!

Are you using Movesense as the chest movement sensor per chance? I've been looking into breathing rate lately, but haven't made the jump just yet.

Thank you! We've integrated a different chip for measuring chest movements

Amazon.de customer service has consistently been much better than anything else in Germany, so it's probably not the law.

It's "loss leader", selling under the price to make your competitors go bankrupt, then use monopoly power.

It's illegal under German law, EU law, and I'm sure it's also explicitly called out as illegal in at least 5 trade treaties Germany signed.

Needless to say, like everything in the EU, it's only enforced against local companies, in this case German ones.

Or, it's easier for Amazon to have a consistent customer experience everywhere in the world. But that would make too much sense?

Yep, I'm sure it's the brilliance of Amazon and not the same old trick of creating a monopoly then exploiting it that people have been using since the early middle ages and regularly outlawed because it destroys economies.

Say ... what was Amazon's initial reason for success? Being cheaper by exploiting the interstate commerce clause to avoid paying sales tax when it's competitors weren't allowed to do so? You don't say. Amazon is famous for losing money on their delivery business (up until recently)? It's constantly repeated in 10+ years of their financial statements ...

So either Amazon has completely changed tactics and become truly brilliant and we still don't understand the plan ... or they're up to their old tricks, being slightly cheaper, now with less legality!

How does this manifest?

This moderate amount of UV is enough to accelerate skin aging which is why we wear sunscreen.

The topic was melanoma incidence, not skin aging.

But even for skin aging things aren't that simple, though sunscreen companies would love you to think that. UV light is a treatment for psoriasis, eczema, and many other skin conditions.

And vitamin D improves symptoms/reduces incidence of "hypertension, cardiovascular disease, stroke, breast cancer, colorectal cancer, metabolic syndrome, type 2 diabetes, obesity, multiple sclerosis, type 1 diabetes, rheumatoid arthritis, Alzheimer’s disease, autism, schizophrenia, asthma, preterm birth, maternal mortality, myopia and COVID-19" (a lot of these are aging related).

Most studies on UV light/vitamin D supplementation have been done in mice, which are nocturnal and don't get the same benefits as us from sunlight. Here's a recent article in pigs:

UV light exposure versus vitamin D supplementation: A comparison of health benefits and vitamin D metabolism in a pig model

Here's a helpful review of the topic:

Are Vitamin D Supplements an Adequate Substitute for Sun Exposure?

https://esmed.org/MRA/mra/article/view/3635

  In this paper we review the current state of the science on this subject and conclude that vitamin D supplements are not an adequate substitute for sun exposure for attenuation of most of these diseases and adverse health effects, particularly hypertension and cardiovascular disease, and should not be recommended in lieu of sun exposure to patients presenting with low levels of serum 25(OH)D. Vitamin D supplementation for such patients could even be harmful, because it will raise patients’ serum 25(OH)D levels, thereby giving patients a false sense of security and obscuring the best available metric for insufficient sun exposure.

Best taken with a grain of salt as this study was funded by the National Cattlemen's Beef Association.

That certainly raises questions.

I am bemused / irked / saddened by the state of nutritional science research. I am convinced that the classic "food pyramid" that was pushed for years was a bad idea, but now guidance on what to eat seems to have split into various warring factions.

Some say that we should severely limit or even avoid meat. Their words look correct on the surface, but I notice their science seems based on "meat" pretty generically. There doesn't seem to be any accounting for eating high end grass fed beef from an organic market vs. low-end beef from a gas station. Does it really make no difference?

Another faction recommends eating meat freely, with no distinction as to type or quality. Another insists on the highest grade meat but then also discourages dairy. Another recommends high quality meat and no vegetables.

I would think that it would be, by now, more straightforward to determine what really makes most sense to eat. I guess (nearly?) everyone seems to agree that adequate water is good and too much sugar isn't.

Red meat or the study ?

For an alternative consider the German-made Creapure, on which a large chunk of creatine monohydrate research has been performed.

I did, but found indication they were sourcing from China, which is the general rule in Germany now for most things. I haven't formally pursued it though. Regardless, it does seem of good quality.

My first choice, being in the US, is still either of the two previously mentioned. Creapure seems a good option if needed.

I would like to avoid China, too, and it looks like Creapure is good. From their site (https://www.creapure.com/en/how-creatine-produced):

"Production in Germany in our own production plant

Creapure® is produced in Germany in a production facility specifically designed to eliminate the risk of cross-contamination and contamination by other products. Not all creatine supplements are subject to the same strict manufacturing standards as Creapure®. Look for the Creapure® logo as a seal of quality. Renowned manufacturers of food, nutritional supplements and sports nutrition products use Creapure® and other high-quality ingredients from AlzChem to produce food supplements to be sold in stores or online."

After re-reading this, I thought maybe they had fooled me with the AlzChem reference, but AlzChem is also in Germany.

They list many brands that use their creatine. Momentous in the US is one that I've heard of before and their price is good ($30/lb (450g). Better than the alternative I've been buying.

CM42 Central is a workable replacement and FOSS but there's definitely room for improvement.
