I saw him speak at LSU about 20 years ago, and I still remember a lot of what he said. The title of the program was "How to Get a Job Like Mine." All of his lectures were titled that, no matter what they were really about. This one could have been titled "Fates Worse than Death," and it was mainly an anti-Cold-War polemic, but he did cover some facts about his job, as well as secrets of love, leadership, and heroism.
Which can be summed up in his remark about the meaning of life:
"We're all here to fart around."
