Update of previous post...

Here's part of the talk by Henry Lee I attended last week:

Lee injected humor into his presentation, joking about what he called “the stages of aging.” The first, he said, is “you forget names.” Audience members nodded in agreement.
“The second stage is you forget faces,” he said, and again those in the audience nodded. "The third stage is when you go to the men’s room and forget to zip up,” Lee joked, and startled audience members laughed.
The fourth stage of aging, he added, “is when you forget to zip down.”
