100% of the fan service containing shows could just be adult cast. I don’t understand why that’s so hard. More adult cast shows in general would be nice. Why’s everyone gotta be a highschooler, man?
that’s why you’d make the level of UVB radiation low enough that people could safely spend 24/7 under it, but high enough that it provides a health benefit
You might not get 100% of your vit D levels this way, but perhaps just a fraction of it. Depends on how the risk benefit calculation works out.
and of course infrared is generally harmless as long as it’s not strong enough to cook you.
That’s not true. We’ve evolved while being irradiated by the sun for literally billions of years. Your body has mechanisms to repair damaged DNA and kill+replace cells that are too damaged. Issues arise when the damage grows fast enough for your body to keep up repairs. E.g. you get a sun burn because you don’t have an adequate tan or you hug a reactor meltdown.
Supplements are an inadequate solution for many reasons.
Vit D supplements barely get absorbed by the stommach. The only way to get adequate vitamin D levels with supplements is to take huge doses for like a month while testing your blood to see if levels are adequate.
Most available Vit D supplements take a week to be metabolized into the active form.
Vit D supplements can give you an overdose of Vitamin D and have severe negative health consequences.
Meanwhile half an hour of sunlight gives you healthy levels of Vit D without risk of overdose.
I’m not advocating for 1000W/m^2 UVB radiation blasting you 24/7, I’m talking about levels that are low enough that you can constantly be exposed to without a increase in risk.
And btw a lack of vitamin D causes severely bad health outcomes, even if it would cause a minor increase in skin cancer (which it doesn’t), the benefits of adequate vitamin D levels would vastly outweigh that risk.
Same with melatonin, supplements can’t replace the effect of exposure to infrared light. But at least with infrared people won’t spread misinformation about how there’s no safe levels.
Ideally our LEDs should emit a safe dose of UV-B and infrared too, because they are vital for vit D and melatonin production, both of which are extremely important for general health. As more and more of us become basement dwellers and winter depression enjoyers, this would help out a lot with public health.
I think that is a feature of Google Assistant or some other Google product. It reads everything you have on your screen at any moment to give you “smart” help like easy opening of addresses or phone numbers.
yeah meanwhile iron is literally nescessary to make your blood transport oxygen. Mo and Be (and their alloys) just have similar strength to weight ratios, but they aren’t exactly practical drop in replacements. So yeah, I haven’t found anything better than steel, there’s just materials that are better in one or two aspects, but nothing with the versatility of steel. To be fair, we have thousands of years of research into steel, perhaps we can still find something better. Idk, maybe some high entropy alloy.
Yeah it’s kind of insane what a miracle material steel is. Especially for how long ago it has been discovered and we still haven’t found another material that is better in every way, like how steel replaced iron or brass or copper. The balance of all the material properties for its weight/volume and its manufacturability and price is just unbeatable.
For scifi purposes,I tried to find another material that could beat it if cost wasn’t an issue and I couldn’t. Closest ones I could find that aren’t already obiquitous in popular consciouness like titanium, aluminium, tungsten carbide etc. are Molybdenum and Beryllium. But yeah, they don’t exactly beat steel either.
