OH!

I guess that it would depend upon my current location, a Red state or a Blue state.

I can totally see me flipping the bit if I were in a Blue state... Maybe in a Blue state with freedom lost zombies, I might be even more proactive about wearing a full M-17 mask and gear for each shopping trip.

Now don't go around triggering the blue NPCs. They'll start screaming about how you're supposed to leave the good stuff for the "essential workers".

I must say I'm on the fence about this. I can truly see his point. That blue state crap needs resistance.

But I also want to not infect others. Too many years working at hospitals breeds a no-harm mindset.

I suppose I'll just have to take a pass on judgment and be thankful I'm in a red state.

We all seal the N95 to the skin with melted wax right?

Tight fitting, vs Loose fitting respirators.
In nursing i was taught pretty easily: they covered your head with a wrapping, and put a very foul smelling chemical under it. If you could smell it, it was fitted wrong. If you couldn't fit it right, you taped it to your face. Not comfortable, but pretty effective.

I actually carry a gun more for others than myself also. The chances of ME being specifically targeted in public are very low, the chances of someone else being targeted in my vicinity are much higher.

I wish the same people who are the most likely to wear masks would also realize that about guns.
While others here would seemingly start shooting guns around the place and then tell someone who's hit they should have been wearing body armor. Can't expect others to keep you safe, now can you, if you're afraid of bullets, you should stay inside in a bunker or wear body armor. No need to keep your bullets contained, according to their logic regarding masks.

If you've ever been given a banana oil test then you have a civilian's good understanding of mask fitting.

It's a universal civilian standard. Military though, likes CS gas and that definitely punctuates the lesson with pain.

95%. 98%. 99%. Almost ALL virus and vapor capable of carrying the virus has dropped below your infectious holes (eyes/nose/mouth) at 4-5 feet. At 6 feet the probability of infection is so low to be a statistical anomaly. The extra 2, 3, 5% you get by using various barriers and designs on your face amounts to no improvement in protection at 6 feet.

The distance a cough sneeze travels is kind of irrelevant. Mucus and saliva, while gross, are not infectious in and of themselves. What is important is the amount of pathogen in the saliva and mucus. There has to be enough to cause infection otherwise it isn't going to do anything. Most people do not just openly cough and sneeze into the air. Most people cover their infection holes at least partially. Others direct it to unoccupied areas in addition to covering.

Personally, if someone is coughing and sneezing in a store I don't make an effort to get close to them, even before COVID. I actually keep my distance, because DUH.

However gas can provide upward force on a respiratory droplet to prevent it from falling,which is clearly what is being demonstrated and explained. 90% of the collection of videos are coming from researchers such as MIT. I originally posted half a dozen from those sources, bit found a single collection video that included them that was a lot less messy for a post.

Yes, if you include a hot or lighter-than-air gas. Otherwise the droplets are at the mercy of gravity and local air currents. Add to that the effects of evaporation. Someone who sneezes, coughs, or breathes is not going to infect someone with COVID 199 feet away.

I learned with sulfurous acid and SO2 from a lead/zinc smelter, while shovelling ore onto belts in 100 deg heat, high humidity, in underground tunnels with deficient O2 content depending upon whether the roaster draft was maintained or screwed up. and no analyzers, no alarms as to when to climb out of the tunnel. Basically if you started passing out, it was time to climb the ladder out and hope you didn't pass out on the way out.

Without the respirator the airway would spasm closed.

Summer job when putting myself through college.
MSA ComfoII with carbon screw in Acid gas filters and particulate filters (for the lead dust) on top of that which would clog every couple hours.

A long, scientific article which means most won't actually read it. But for those who are interested, testing shows a properly constructed cloth mask can be almost as effective as an n95.

And as we should already know, fit is the most important factor and can influence the results by 50% or more.

One layer of 600 thread per square inch cotton material, often found in sheets, is 98.4% efficient at corona scale particulates, compared to n95 which is 99.9.
I don’t believe that. Trump doesn’t wear a mask so why should I? Jk, no!!! A mask made out of cloth will not have the same seal. I often wear a respirator with p100 filters if I know I will inside a crowded area like say the supermarket. I think that’s better than any practical mask including N95. Plus, respirators are immediately rewash-able for re use
