I’ve been thinking about my lungs lately, especially as we recently passed the third anniversary of the week the world shut-down due to a microscopic lung invader. Don’t worry, I’m not going to preach about COVID. But I’m going to forego the usual travel blog this week to let my science nerd out. If you’re not into this, that’s fine, but I hope you’ll take a moment to at least wonder why millions of people in the world are still wearing masks, and why wearing a mask, for most people, is simply not the big deal that it is in the USA.
