Episode notes
Age Is Not A Reliable Cognitive Signal
- Age alone is a poor metric for judging a leader's cognitive fitness; observable signs like gray hair or slow speech are unreliable.
- Dr. Charan Ranganath urges assessing actual cognitive abilities and emotional stability instead of superficial cues.

- Memory errors often reflect retrieval failure, not permanent loss; tip-of-the-tongue moments are common and benign.
- Forgetting with a capital F indicates true memory loss where experiences vanish, a distinct and serious condition.

- Repeated retellings add imaginative elements and external details, making memories dynamic and fallible.
