It already was in the several decades where he didn’t age, though, so something REALLY fucking stressful must have happened in the mid to late 90s.

Something much more stressful than everything we know happened to him, including checks notes

• the Holocaust,
• several families dying gruesome deaths, and
• being in solitary (other than his nemesis beating him at chess once in a while) confinement for several years.

Must have stepped on a Lego or something 🤷🏻
