I really like this analysis.
He doesn’t say so explicitly (comes close), but I might add that sometimes when something seems weird and you’re asking why, it actually turns out it’s not surprising at all, it’s quite natural, and the real question is, “why not?!”; the weird thing is that in our everyday experience things are actually quite weird.
During the time of this video, I’m pretty sure he’s well into his stomach cancer and I think I can detect that he’s uncomfortable. I’m so glad that he nevertheless was in the mood to do this and to share his excitement.
