Imagine you’re dead. You’re floating up through the clouds, heading for the pearly gates, and you turn for one last look at this green-and-blue planet and whatever you did with your time here. What’s going to be on your mind? If you’re reading this, you can’t give me a factual answer to that question. So guess. People will be on your mind, right? You might feel love, or grief. Or surprise [“Wait, I’m dead? Like, dead dead?”].
