You could look at its glycosylation. One of the things that makes you unique as a human are your patterns of glycans on your cell surface. For example, only humans and a few other extreme rare out outliers produce sialic acid while all other animals produce hydroxylated sialic acid. The glycome tells you a ton about what species you’re dealing with. You can tell the difference between bacteria vs fungi vs monkey vs fish vs human cells by looking at their sugars alone.

You'll be happy to know our work clothes are also spf50. If you work in the trades, the shirts have to meet this standard. People were getting burnt through thin cotton t shirts.

It makes no sense to me. Bugs are gonna get freaky and copulate then you bring it inside to fold and store or wear.

Makes my skin crawl.

I would add an interesting chemistry tidbit that has to do with colors.

Different chemical bonds will absorb different wavelengths of electromagnetic energy depending on how stable they are. In organic chemistry, a lot of times that has to do with how much electrons are delocalized (or “have the freedom to move to different bond sites”) over large numbers of double bonds. If you look up the structure for carotene (the chemical that makes carrots orange), you’ll notice a ton of these alternating single and double bonds. The electronics are delocalized over that whole stretch. That pushes the absorbance to higher wavelength. A lot of molecules of colors have a high degree of stabilizing electron resonance like that. Tomatoes have even more conjugation so they absorb higher up into the red wavelength region. In general, all those are high wavelengths for chemical bonds to be absorbing, which is why it takes so much conjugation. More typical bonds with less conjugation will absorb down in the UV spectra or lower wavelengths.

Here’s a source that talks about some colors in food and their chemical structure. Oh it has blueberries too! That molecule looks super cool. :)

If you want to experience the most loving solar embrace visit the Altiplano in December and play a football match at 3500m! The sun is exactly directly overhead, and the UV index is over 20 every day. The crazy thing is, it’s the craddle of South American civilisation.

They suggest a 30+ for everyone nearly everywhere if you don't want to look like a leather sack at 70.

Thank to everyone contributing.

I am going to use your concepts for a NDIS appeal at the AAT. (Australia).

The NDIS will not fund a path to a blind client’s clothesline (multiple falls) - “we only find 1 access path to a dwelling, and a clothesline path isn’t access”.

She is also immunocompromised and uses the Sun to sterilise clothes a sheets. “Why doesn’t she use a clothes dryer and a dehumidifier”.

This sub is gold. Thanks.

Edit: fixed typo, and added Australia

HA. Only two hats.

Amateur.

I too Slip on the first hat, Slap on the 2nd, but the trick is to Scrunch on the third hat to hold down the slippy slappy first two hats.

But then, I only go outside at night, so I keep losing hats in the dark , unless there's moonlight .of course

Flonase, saline spray, occasional Claritin, and still have post nasal drip more than I'd like

It probably means they are perpetually on a shitload of antihistamines.

That's awesome! Thank you

The Galactic Center of the Milky Way is a supermassive black hole called Sagittarius A*, which has a mass of approximately 4 million times that of our Sun. While the black hole itself does not spin, the material around it certainly does.

The rotational speed of the material orbiting Sagittarius A* depends on its distance from the black hole. At a distance of about 0.01 light-years (0.003 parsecs) from the black hole, stars in the vicinity orbit Sagittarius A* with speeds of around 1,000 kilometers per second (621 miles per second). However, at a distance of about 1 light-year (0.3 parsecs), the orbital speed of stars drops to around 200 kilometers per second (124 miles per second).

It's important to note that these speeds are relative to the black hole itself, as there is no absolute reference frame in space. Additionally, the orbits of the stars around Sagittarius A* are influenced by the gravity of other stars and objects in the vicinity, which can cause their paths to be perturbed and altered over time.

I’m now wondering what the effect of low e coating does since that blocks a lot of the UV coming through.

so you just don't go outside or open windows?

We have light 'spf 15' ones but they're mostly face lotions and such that are meant to be worn under makeup or indoors.

For outdoors we have spf 30 or 50 generally. After 50 the protection doesn't increase much so spf100 isn't much better than the 50.

I know our sunscreens have to go through testing and meet regulations but I assume the rest of the world does that too.

We have a long long running TV add campaign called Slip, Slop, Slap, Seek, Slide.

Slip on a hat, Slop on sunscreen, Slap on a hat, seek shade, slide on sunglasses.

Edit- Slip on a Shirt

Hence why I carry an arc welder with me at all times. High UV and the heat evaporates any germs. While all my doorknob may not be able to turn anymore, they are exceptionally clean
