Not tag teaming Userq here... but I was gonna post the exact same thing lol. Probably a good idea while riding the bike with the life-vest next to the pond, to wear a meteor helmet too. No I don't think it self destructs, or at least I have no idea how long it lasts but that's not the point. Pollen.... Pollen is actually a winged particle. For real. Mother nature I guess. So its designed to move around. Now, I have a pine tree at one end of my drive, granted its a big tree but when that thing does its little annual pollen bit in the early summer.... that one tree dusts the entire asphalt driveway and anything else around. One tree. I mean its everywhere. That one tree probably puts out more pollen grains than... I have no idea. Covid is .125 μm, pine pollen is 6 µm... so 48X larger. From the National Institute of Health: Respiratory droplets can be of various sizes and are commonly classified as aerosols (made of droplets that are <5 μm) and droplets that are greater than 5 μm. Although the fate of these droplets largely depends on environmental factors such as humidity, temperature, etc., in general, the larger droplets settle due to gravity and do not travel distances more than 1–2 m. The use of physical barriers such as respiratory masks can be highly effective in mitigating this spread via respiratory droplets. Filtration of aerosols follows five basic mechanisms: gravity sedimentation, inertial impaction, interception, diffusion, and electrostatic attraction. For aerosols larger than ∼1 μm to 10 μm, the first two mechanisms play a role, where ballistic energy or gravity forces are the primary influence on the large exhaled droplets. As the aerosol size decreases, diffusion by Brownian motion and mechanical interception of particles by the filter fibers is a predominant mechanism in the 100 nm to 1 μm range. For nanometer-sized particles, which can easily slip between the openings in the network of filter fibers, electrostatic attraction predominates the removal of low mass particles which are attracted to and bind to the fibers. Electrostatic filters are generally most efficient at low velocities such as the velocity encountered by breathing through a face mask.
You do realize this is travel distance not due to wind, right? That's obvious to you, right? That's where the 6 feet comes from, even indoors, where there's no wind. Again, you never explained how a masked sneezer's mask can block covid, but the mask worn by the guy next to an unmasked sneezer can't.
While you two are busy trying to find research proving the wind can't blow covid; I see I need to address this too: If you play the lotto etc., you have a slim chance of winning. Yet people win regularly. And if you do win, it could be life-changing. Same with covid. Play stupid games--long odds or not--you can win stupid prizes. Hope this helps: Infectious disease: Blowing in the wind https://www.nature.com/news/infectious-disease-blowing-in-the-wind-1.10374 "... Epidemiologists now have a new place to look: on winds blowing from central Asia. A team of medical and climate scientists, including Burns, argue in last November's issue of Scientific Reports1 that the agent of Kawasaki disease is not only reaching Japan from the Asian mainland by this route, but it seems to be crossing the Pacific Ocean to infect children in Hawaii and the North American mainland. If windborne spread turns out to be true, the Kawasaki disease agent will be the first viable human disease pathogen proved to cross thousands of kilometres of ocean by natural means (as opposed to carriage on planes or ships). And it may not be the last: researchers are beginning to ask whether the wind might also be a factor in the spread of influenza. ..." Anymore questions?
From skin cancer. You will probably get skin cancer. That's how the universe works. Or are you using sunblock? If so bad news on your vitamin D.
