The following is in no way scientific. It's just an analogy.
And, this is in no way intended to start another one of those nasty threads where talk about coronavirus goes political. So, please, just don't.
But, I just today heard an analogy intended to encourage mask-wearing (not so much for your own protection, but the protection of others in case you're an asymptomatic carrier), and I loved it. It summed up -- much more succinctly than I could have otherwise done -- the gut instinct that I had back in March when the "public experts" were telling us, "don't wear masks, they don't help and might even hurt" ...and I thought to myself, "Y'know, I'm not sure precisely why, but I'm pretty sure they're either wrong or lying."
Here's the analogy:
If a guy's standing there, facing you, with no pants on, just naked from the waste down,
and he starts urinating in your direction,
your shoes are going to get wet, right?
Now: How would the situation have been different, if he had only been wearing some pants?
...
(Makes perfect sense to me.)
...
(Except the part about
why there's a guy facing you with no pants on. I'm not sure about
that bit, but hey, your business is your business.
