This is something I’ve heard a lot, and assuming it’s true, what’s the science behind it? Surely holes in masks are the same size no matter whether the germs are heading in or out, but I’m guessing it’s not about the holes and I’m missing something.
Obligatory disclaimer: I’m not an anti-masker, I’m still wearing it in shops for example. This is just me wanting to understand.

Imagine some guy decides to pee on your leg. If you’re wearing pants, they will partially protect your legs, but not really. If he’s wearing pants, this will stop any pee from getting on you by a lot. But if you’re both wearing pants, you should walk away without any pee on your legs. I think I heard this on Reddit but the image stuck with me and I think would really resonate with a 5 year old.
