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.

Scooter Duff's Theory of Cosmology [A work in progress]

 [Olde Duff Gets Seriouser] SUPERMASSIVE BLACK HOLES  ARE MOSTLY PRIMORDIAL  DARK MATTER [Draft 8/19/2023] 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 could.  There was a vast quantity

Rick and Morty

A Millenial Hit Olde Folks Don't Know About Are you over 50? Have you ever heard about "Rick and Morty?" I thought not. There is a "cell" of younger people who love the show and say extravagant things about its wonderfulness. In these times when prior punditry had it we would be unified by some mysterious power in the Internet, there are more and more cells of people, unified within their cells, but isolated from most of the other cells of special interests*, tastes and proclivities.  The U.S. looks more like a pomegranate than a cantaloupe - to push the fruit/melon analogy to its extreme. I will dream up a graphic one of these days. USA, USA! society in fruit form. ANYHOO... I watched Rick and Morty at my millennial son's suggestion, and I LOVE IT. Eccentric old genius and non-genius grandson as the lead characters (faintly Back to the Future -esque) + sci-fi + Simpsons sensibilities +  intelligent satire + over-the-top imaginative creators

An Informational Present

I TOLD YOU ABOUT THIS SIX YEARS AGO (Surely you remember ?)  ...And in those six years, multiple research projects have affirmed and reaffirmed that SENOLYTICS is a big deal. The science of senolytics: how a new pill could spell the end of ageing                                    * I'm reminded of this by a well-researched article in The Guardian , a newspaper I respect. Aside from that hyperbolic, click-bait-ish headline, it's a fair summary of the state of knowledge on the subject. In brief: Certain drugs and several supplements help the body get rid of senescent cells, "zombie cells" that don't die after they quit doing their thing and just hang around spitting out inflammatory chemicals that damage various organs, joints, and brain cells. The senolytic agents augment apoptosis , nature's way of killing off the senescent cells. When those senescent cells are gone, things start improving measurably (see the mouse with the young look in the Guardian piece.)
