Why Are You Wearing Half a Mask?

MASKS THAT ONLY DO HALF THEIR JOB


The masks with an exhaust valve are all the rage because the air in the mask stays less hot/humid if you don’t have to exhale through the filter body; BUT only your inhalation gets filtered.  

THIS PROTECTS ME FROM YOU, BUT NOT YOU FROM ME
OK, I'm really, really selfish. Got a problem with that?










It’s being Exposed* that this kind of mask only does half the job. It protects you but does not protect others from you. Your aerosols escape unrestricted, unfiltered and as infectious as if you had no mask. There will be a huge stink about this disclosure.
EVEN THE MIGHTY N-95 IS DEEPLY FLAWED BY AN EXHAUST VALVE


 Ahead-of-the-curve magazine, 
 
                                                                           is already on the case:

  • Experts are warning the public against wearing certain types of N95 face masks with front valves.
  • They say the masks protect the people wearing them but do not stop virus droplets from escaping and infecting others.
  • These masks are designed for construction workers to use to keep out dust and other particles.


The word is getting around.  I harangued an old pal with this news and he said, "You are so correct about the masks with exhaust valves, they only protect the wearer.  I recently had my annual physical and the doctor’s office required all patients to wear masks and specifically forbade any masks with exhaust valves."

 *Google (or Bing or Yahoo or Duck Duck Go) "face mask with exhaust valve" and you will see a lot of confirmation.  Then contribute all those valved masks you bought to the nearest coal miner or construction worker you know.

This has been studied by NIOSH. Exhaust valves on proper NIOSH masks are not a problem. https://www.cdc.gov/niosh/docs/2021-107/default.html
The CDC has issued guidance.

Teddy and Bernie

Image
By Gosh, I Think I've Got It! Bernie caught some gaff for having a narrow focus campaign. Here's how he's going to broaden it out. IMHO. And that doesn't mean he's running for anything,  just being Bernie. * Teddy as the model for... ...The New Bernie campaign? * I was zapping through the pile of political pitches I get everyday on my old fashioned e-mail (wduffer@aol.com), zap, zap, zap... Congressmen from Colorado, Florida, Ohio... on and on, Democrats I never heard of, but I'm on "The List." I don't get irritated, I just get rid of the ads; I mean after all, they're Democrats. After I finished my zapping, I had a snack and set to recording another audiobook chapter. Then it hit me, based on one of the ads I zapped.  Here 'tis: It was when I dragged it up again that I noticed it was a Bernie ad, and I said, "That's it!" Do you how many great quotes flowed from Teddy R? About half of them ar...

Scooter Duff's Theory of Cosmology [UPDATED 5.4.24]

 [Olde Duff Gets Seriouser] SUPERMASSIVE BLACK HOLES  ARE MOSTLY PRIMORDIAL  DARK MATTER [Draft 8/19/2023] [UPDATED 5.4.24] & [9.25.24] THE BIG NEWS.. ..Is from the James Webb Space Telescope. There were furiously active galaxies very soon after the Big Bang, not that long after the first generation stars happened. This implies supermassive black holes at the centers of the new galaxies.  The question, "how did these giant black holes get there so early?" seems not quite answered by the two main contenders, "Giant dust collapse," and "Many stellar black holes consolidating." Thus I decided to toss this hat into the ring: At the big bang, and dark matter was the first matter of any kind to form (perhaps during the mysterious “inflation” event -- my personal theory).  It’s mutual gravitational attraction and lack of interaction to any electromagnetic force allowed it to exist and start to coalesce, even in the heat of the BB, long before baryonic matter ...

Bot Spotting - Seriously

Image
If you have opinions, and you have "proof," better check your sources! TWITTER IS THE BOT SWAMP Here is a detailed method of spotting bot tweets; twelve techniques: The trick in some cases is finding the non-human  number of tweets. @BlackManTrump, a hyperactive account, posted 89,944 tweets between August 28, 2016 and December 19, 2016 (see archive   here ), an average of 789 posts per day. The account  @sunneversets100 , an amplifier of pro-Kremlin messaging, was created on November 14, 2016. On August 28, 2017, it was 288 days old. In that period, it posted 203,197 tweets (again, the exact figure can be found by hovering the mouse over the “Tweets” entry). Watch for " Amplification " When a fake news story gets re-tweeted a bunch, you might think "Gee, it must be true. I see it everywhere." You are the victim of classic BIG LIE propaganda technique in the social media world. Remember, the Russians are the world leaders in weaponiz...
