"Travels" opens with stories of Michael Crichton's clinical rotations as a medical student, told with a spirit reminiscent of Richard Feynman--curious, sensible and irreverent. The tales are as funny as they are disturbing: a healthy patient convinced that he is dying of "aerial nodes," a neurology resident who, "in a kind of insane pretense," sticks pins in incurable patients "to check their reflexes." Unifying these stories is Crichton's conviction that feelings can have as much of an effect on the body as physiology; at one point he asks patients: "Why did you have a heart attack?"
After Crichton leaves medicine (while he faults the profession, one suspects his departure was also motivated by hefty royalties from his best-selling thriller, "The Andromeda Strain"), he spends some time seeking out adventures in exotic locals such as Bangkok and Pahang. Soon, though, his geographic peregrinations become incidental; the real travels are in his mind, as he moves from being a rational, linear thinker, concerned with "making things happen," to more of an open-minded mystic, captivated by psychics, auras and channeling.
