I called up Aaron Carroll, a doctor and writer in Indianapolis, because I was trying to figure out how to feel about masks.

And I knew he'd have opinions.

And it's now recording. Okay. Yep.

To be clear, I wasn't sure if I was going to agree with Aaron's opinions.

Okay, so Aaron Carroll, you're a doctor. I'm going to ask you a question, and I want you to be

honest. How many masks do you have in your house? Literally zero. Really? Literally zero.

When Aaron told me this, I was surprised.

In the last few days, there have been multiple reports that the Centers for Disease

Control is about to issue new guidelines, saying the general public, all of us should

consider wearing masks when we go outside.

Back in February, you tweeted, masks are mostly to protect others from you when you are sick.

Correct.

Not the other way around.

Correct.

Please don't waste them.

Correct.

Leave them for those who have a real need.

I'm still consistent in that.

I think that that is utterly true.

This is the part where I should tell you that in my front hall, I've got masks.

Just four of them.

Surgical masks.
