and this is your brain after a day of preparing to teach entirely online:

This is a melted green rubber duck I found online, and I find this to be a pretty accurate representation of what my brain feels like right now. I sure hope I sleep well because I’ll need all those hours of deep non-REM sleep to process everything I’ve learned (newer data suggest this stage of sleep is the most important for learning and memory, and that’s from John Hopkins, so I assume it’s legit).
As for the part of my sleep that involves dreaming, I hope it has nothing to do with screens, elbow bumps, or masks.
