Dr. Smith, a psychologist and college professor emeritus, enlivens her world travels aboard cargo steamers by studying the behavior of her fellow passengers, most of them elderly retired people like herself. She offers some interesting practical advice for those who decide to travel when past age 60, and also mentions reasons why certain types of persons should stay at home. For those who are compelled to remain behind for reasons of health or obligations, she points out that it can be fun to keep track of the travels of friends. Younger people whose parents seek to travel can profit from many of her suggestions about creating a favorable emotional climate for the embarkees. Among and around the topical material there are many lively and charming descriptions of sights she herself has seen.
