Q. I love your new book, Longevity Lifestyle Matters, coauthored with Briggs and Horton. It's all stories, much like your Chronicles series and Adventure series. It's so much easier to remember ideas from a story. What prompted you to use a story format?

A. I think you just answered your own question. Rudyard Kipling once said: If history was told in the form of stories, it would never be forgotten. To paraphrase in my own words, I tell stories about health and brain function because the information is easier to remember—and if you remember it you might just implement it.
