In Ge Hong's A Handbook of Prescriptions for Emergencies (肘后备急方), I noticed one sentence "A handful of Qinghao immersed in two liters of water, wring out the juice and drink it all" (青蒿一握, 以水二升渍, 绞取汁, 尽服之) when Qinghao was mentioned for alleviating malaria fevers. Most herbs were typically boiled in water and made into a decoction before taken by the patients. This unique way of using Qinghao gave me the idea that heating during extraction might have destroyed the active components and the high temperature might need to be avoided in order to preserve the herb's activity.

There’s one book I’ve given the most in my life, which is a book called – well, there are several now that I think about it. There’s a book by Timothy Wilson called Strangers to Ourselves , which is one of the loveliest, most insightful books about social psychology that I ever read. And I give that a lot to people. And every time I meet, and really, I’m always meeting people who work in retail, particularly I always send them, particularly if they’re Jewish, I send them a book called The Merchant Princes . It’s a book about the great Jewish retail families of America. So in the 19th century, all of these people come over from Europe who have experience in the garment trade or retailing. And an extraordinary number of the early 20th century/late 19th century department stores pop up around America are founded by Jewish immigrants from Europe from, literally, you go to any town in America, the traditional department store is from one of those families. Well, a guy, and I’ve forgotten his name, wrote a book about those families, and it’s called The Merchant Princes , and it’s fantastic.

A book also pushed me to become a medical doctor. I was deeply inspired by Torao Tokuda, a physician who founded a hospital group in the 1970s that tried to revolutionize the Japanese medical care system.

All right, I'm going to give you two, because they're kind of categories to it. I'd say the first one underneath this health and human performance realm, Diagnosis and Treatment of Movement Impairment Syndromes. It's a Shirley Sahrmann book that I think is landmark. I mean it's decades old, super impactful. Kind of reads like stereo instructions, so you're going to go through a page at a time. But Sahrmann is still a practicing physical therapist at Wash U in St. Louis.

Probably the biggest impact for something less than $100.00 would be a mole skin diary. I’ve got them all lined up for every year. I’ve had them since 1986. So, in there, in a very tactile way, I have like lists in the back, movies, books. And then, I write in the back the name of the book and then who recommended the book.
