Can you explain the chest wound on your right side part?

In the movies, a chest wound (like a gun shot) on the right side means, "Phew, it missed their heart!"

IRL, that injury on either side is equally worrying.

I'd be more concerned about Chinese suppliers who have privately said they would supply faulty equipment related to corona virus to the US.

Can you provide a source for that? It smells of a rumour people might spread to sow mistrust.

wechat posted on twitter, good luck finding it though

3D printing seems crazy for a single sheet of bendy plastic that needs to be mass produced. Cutting them out by hand with a knife or a scissors would be better than 3d printing, never mind laser or die cutting.

I'm not sure what the person above is talking about. I haven't seen a single face shield design involving a 3d printed piece that didn't also require a sheet of bendy plastic cut to fit with that 3d printed piece.

I was laser cutting the clear parts of the shields with a local makerspace. We ran out of the thicker material that was being used, now there is a worldwide shortage. We were making for doctors and nurses in hospitals, so we wanted something more substantial. These look pretty flimsy, but are probably better than nothing. We failed to realize the supply of our material was not infinite. We actually had a fair number of people 3D printing, but that was still a major bottleneck.

> Face mask + goggles fully covers the 3 places the virus can enter (mouth, nose and eyes) I believe face masks are only 95% effective at best and that's only with a proper N95 which a lot of medical staff appear not to be able to get hold of. Hence they're wearing things like Buffs or cycling masks to make do. In that situation, having another layer that can stop droplets etc. from reaching the mask in the first pla…

An N95 respirator is rated to block at least 95% of 0.3 μm particles. It’ll do waaay better than 95% at blocking droplets! They’re much larger. (though N99 and N100 respirators do exist)

But remember that a respirator blocks 0% of particles getting in your eyes.

But if you have to breathe in infected air, doing so with your nose is far better than your mouth, since your nasal cavity has thicker membranes and a lot of mucus and hairs to catch particles, whereas through your mouth the particles are going straight into your lungs. In fact, that effect might be so significant evolutionationary that it is the reason we have a seperate nose and mouth, rather than combining the two…

A nose lets you breathe while you eat.

Put a peg on your nose... You won't have any trouble eating after a few minutes practice. You just breathe between chewing.

The biggest problem is actually eating hot food - it seems the mouth can withstand hotter foods than the lungs, which get painful if you breathe in the steam from the half chewed food in your mouth.

It says that there's massive inequality?

I don't think it says that at all. You can't cherry pick two particular institutions and draw some sort of conclusion about "society". In this particular case it seems like the entire conclusion is based on nothing other than preconceived notions of what reactions "Stanford" and "Oakland" trigger in the reader. There doesn't seem to be any particular details about the actual situation at either location and how those…

For reference, one of those institutions is in Palo Alto and the other is in Oakland. While Oakland has been massively gentrified it's still much more affordable to live in compared with Palo Alto.

Both of those things seem just as hard as managing a mask. People are crap at handwashing, and face touching is subconscious.

You inadvertently touch your face way more often when wearing a mask, that much is pretty obvious. You also are more likely to be more confident about your safety and behave in a slightly more risky way. Kind of like how cars drive closer to bikers with helmets than bikers without them.

I have found exactly the opposite. I mostly wear a mask because it stops me touching my face.

It's the same mentality as people buying guns. What situation that could conceivably arise from a pandemic requires an automatic rifle? It's a generalised sense of "bad things are happening, I need to be prepared for bad things to happen to me".

> " What situation that could conceivably arise from a pandemic requires an automatic rifle? " Good thing that automatic rifles aren't available for sale to the civilian market[1] then, I suppose. [1] Yes, the pedants will point out that it's theoretically possible with special licensing but it's very uncommon.

Apologies for not understanding the differences between various types of gun and misusing the term.

Still, the point remains - what situation could possibly arise from a pandemic that would require a ?

> What situation that could conceivably arise from a pandemic requires a [semiautomatic] rifle? Rioting, looting, people breaking into your home, police “sick outs.” See what happens if the electricity goes out or all stores are forced to close.

I've seen what happens when the electricity goes out and stores are forced to close - people are really nice to each other and help each other out whenever they can.

Let me put it another way: if you owned a gun, would "the electricity is out" be a reason to shoot someone?

Why unfortunately? I'd say it's quite fortunate that grocery stores and gas stations are still operational.

It's unfortunate because these people are having to put their lives at risk, unexpectedly. They didn't ask to be on the frontlines. In addition, many of them haven't been able to get hazard pay or adequate sick pay.

And some of them (especially within those fields) may be forced by their employer to work part-time and not be eligible for employer sponsored health insurance.
