You're thinking about it backwards.I for one do not advocate for wearing a mask. My reasoning is really very simple and has much logical merit. If the mask the person is wearing by choice works as intended, why do I need to wear one ? Evberyone weariong a mask will be protected from me. No one seems to be able to answer that.
The science is that...
Exactly. Wearing a mask is more protective for others than it is for you. Wearing a mask is something you do because you care about the health and safety of your neighbors and community.... the generic masks are most effective at stopping outgoing virus - keeps an infected person from infecting others. That they are less useful in stopping incoming virus.
I think the best analogy for wearing a mask is putting your shopping cart in the cart corral. Putting your cart in the corral isn't going to save your car, but if the wind picks up, it's going to save someone else's parked car. Except now instead of talking about a dent in a car, we're talking about a deadly disease.
