Astrophysical experiments. Woke up at 6 in the morning. Tolya isn’t sleeping; he’s floating around the station with a camera. I ask: “Why aren’t you sleeping?” “My kidneys hurt.” Tolya is hanging in there through this situation — good for him. Unfortunately, my doctoring abilities are limited.

Our doctor Kobzev came on the link first thing in the morning with the question: “Is Tolya in pain right now?” I couldn’t hold back and said: “You need to think about what you’re asking in front of everyone — there’s a separate channel for that.”
