We asked the experts to answer questions about all the places coronavirus lurks (or doesn’t). NYTimes

Relevant quote to the PeterB/Sarcany debate from Roger's NY Times link:
NYTimes wrote: Why is it that small droplets and viral particles don’t typically land on our clothing?
I asked Dr. Marr to explain further, since we’re all getting a mini lesson in aerodynamics.
“The best way to describe it is that they follow the streamlines, or air flow, around a person, because we move relatively slowly. It’s kind of like small insects and dust particles flowing in the streamlines around a car at slow speed but potentially slamming into the windshield if the car is going fast enough,” said Dr. Marr.
“Humans don’t usually move fast enough for this to happen,” Dr. Marr continued. “As we move, we push air out of the way, and most of the droplets and particles get pushed out of the way, too. Someone would have to spray large droplets through talking — a spit talker — coughing or sneezing for them to land on our clothes. The droplets have to be large enough that they don’t follow the streamlines.”
So, if you’re out shopping and somebody sneezes on you, you probably do want to go home, change and shower. But the rest of the time, take comfort that your slow-moving body is pushing air and viral particles away from your clothes, a result of simple physics.

When you feel like you've vested a lot of resources into developing some expertise on a subject, realizing that you've said/written something wrong can lead to some emotional turmoil and having it pointed out publicly can seem like an assault.
I've been there, myself. It's a sign that you need to take a break from the forum.
You've strongly implied that going outdoors and breathing the air outside is a life-threatening proposition because some random plague-carrier could have infected that air hours ago.
My counter-proposal is that you take a walk outside and clear your head.
Projection abounds... jeezo. Read the articles and make up your own mind, but please do not propose that you know what's going on in mine. And I never proposed what you claim I proposed, I said it's a possibility, which it is.
Edit: Sam3's quote could be interpreted in a number of ways. If we are pushing particles out of the way as we walk about, doesn't that also imply that we're breathing them in too? I'm wondering about the choir group of whom many got infected, despite doing social distancing, etc. https://www.latimes.com/world-nation/story/2020-03-29/coronavirus-choir-outbreak (Admittedly, the choir group was in an enclosed space.)
Here's a relatively balanced view on the subject: https://www.sciencemag.org/news/2020/04/you-may-be-able-spread-coronavirus-just-breathing-new-report-finds

Sam didn't quote the operative part:
How much should I worry about contamination if I go outside to walk the dog or exercise?
Your chances of catching the virus when you go outdoors is extremely low, provided you’re keeping a safe distance from others.
“Outdoors is safe, and there is certainly no cloud of virus-laden droplets hanging around,” said Lidia Morawska, professor and director of the International Laboratory for Air Quality and Health at Queensland University of Technology in Brisbane, Australia.
“Firstly, any infectious droplets exhaled outside would be quickly diluted in outdoor air, so their concentrations would quickly become insignificant,” Dr. Morawska said. “In addition, the stability of the virus outside is significantly shorter than inside. So outside is not really a problem, unless if we are in a very crowded place — which is not allowed now anyway. It is safe to go for a walk and jog and not to worry about the virus in the air, and there is no need for an immediate washing of the clothes.”
Give your ego a rest, Peter.
You are better than this.
You don't have to be right all the time.
