What time do you usually have your last cup of coffee?
How it was made: ChatGPT helped me talk through the topic and script, and Codex helped with the code animation and rendering; the voiceover is AI-generated. I had a hand in deciding the direction, the visual choices, and the final review.
The visuals are simplified illustrations; the five-hour half-life is just an example, and it varies a lot from person to person. Sources: NHLBI (NIH), EFSA.
