Iodine deficiency of some kind isn’t all that rare actually - even in the first world. Severe iodine deficiency used to be very common in the Midwest, with supplementation in salt increasing IQ in the region by double digits. 70% of UK people tested in a 2011 study were iodine deficient. It remains one of the most common micronutrient deficiencies worldwide.

I kind of worry about it coming back, as restaurant, fast food and processed food is commonly not using iodized salt, and at home ‘sea salt’ that hasn’t been iodized is trendy. Dairy is another important source of iodine but processing facility changes have reduced milk content. This opens the door to more regional or sub population deficiency

Iodine is in seawater so was part of the environment of early life. This meant that evolution incorporated it into its core chemistry - it was always around. As animals arose on land some areas were iodine deficient but the element was firmly in biology by then

Does this one correct for all the sick and old people not drinking (or quitting) due to illness? In many studies it is a tricky variable to adjust for, I wonder if others think this one was done well

Amsterdam (and the bulk of the Netherlands) is almost perfectly flat, so biking is easy, the cities and towns are older, so densely built which makes biking convenient, and the weather is milder, without extended periods of heavy snowfall. Does rain and does get cold, but people in Copenhagen are crazy like that and will bike through it.

For this to happen elsewhere like in NA you need an urban redesign to cram a lot of people into much smaller spaces. Which I’m somewhat game for

Miele as a brand is tough - it's super high quality and does tend to last a lot longer, but it's super, super expensive. I was looking at fridges and the Miele 36 inch french door freestanding counter depth fridge (a common size to buy these days in North America) is like 16k CAD plus tax. A midrange mass-market brand equivalent is like 3-4k. Yes, the Miele will work a little better, yes, the Miele will last longer, but the repair bill for a Miele is really steep and the upfront cost is painful. I'm having a hard time justifying the differential.

If the math was even close then I'd buy the Miele purely to avoid replacing an appliance in ten years (which I HATE doing for waste, ecological and hassle reasons), since it should last more like 15-20. This is just such a huge difference it's frustrating as a gap to bridge.

It is more complicated because the UK is a flat island next to the ocean, with winds blowing from west to east. Oceans moderate temperature even up north. It’ll be colder overall but not as cold as Toronto, which has a continental climate with a lot of mountains and land between the city and the ocean. Maybe Vancouver minus a couple degrees in London?

You are developing some mental illness due to what seems to be overwork. If you want to prevent it from progressing further, you need a break where you actively try to heal. Like maybe a couple of days of rest and deliberate stress reduction, then a few days of satisfying your needs like making sure you have a good social group, feel some pride in yourself and your lifestyle (like cleaning up yourself and your home) and maybe consider some light volunteering or something.

You seem really burned out and you have an opportunity and responsibility to address that. It won’t get better without actively fixing the issues (overwork, poor self care, weak social networks, etc),

Consider what your body is adapted to over millions of years of evolutionary history. Go back in time ten thousand years, a blip in that history but to a lifestyle that is reflective of the other millions of years.

Your ancestors spent lots of time outside, did physical activity all day, ate whole unprocessed food, didn’t have screens and cars and light switches, and didn’t sit down for huge periods of time.

Science is finding that as we deviate from those things we develop illness, our bodies don’t handle it well. Your body needs to move a lot to work properly, sitting or lying down all day is not what it is adapted to and its systems break down. Blood doesn’t flow properly, raising clot risk. Bones soften, muscles atrophy, postural issues develop, important hormones get out of whack, risks of metabolic syndrome increase, heck even sexual function deteriorates.

Thing is, people are adapted to an environment where we HAD to be active and work a lot, and we have an instinct to minimize energy expenditure within the framework to conserve calories. If the natural situation where a lot of work is inevitable is gone, turns out we can often be pretty lazy and not move much at all. Fighting that instinct is super hard.

This paper is basically deliberately misleading and frankly does the opposite of what scientific research is supposed to do - work to slowly improve humanity’s understanding of the world. Characterizing dental associations popularizing fluoride to prevent cavities (which it does) as some kind of ‘private lobby’ and associating them with the groups pumping carbs is a disservice.

Yeah, but if there was a huge advantage like skipping three months of potato-like infancy, women would shift rapidly genetically. That isn’t a barrier if it already exists in the population


grumble11 t1_ivc49z6 wrote

Not just that, but calories - the brain takes up a huge chunk of calories during infancy, massively slowing development, requiring more calories and making kids more vulnerable to famine

His work and that of other ‘new weird’ authors give me faith in the future of speculative fiction again. So much got stuck in the same tropes that I got bored of entire genres, but he fixed it by doing something truly and deliberately new.
