Work excluded, the answer is Rockets and Math.
I recently rediscovered my interest in math and occasionally watch long math videos on YouTube. I’m subscribed to Mathologer, but I let myself be tempted by other YouTubers. The social networks noticed and started trying to challenge me with high school level tasks.
I would also watch some rocket launches live. The next on my list is the chopstick attempt – Starship 5.
