Fixx was a member of the high-IQ club, Mensa, and published three collections of puzzles: Games for the Super-Intelligent, More Games for the Super-Intelligent, and Solve It! The back flap of his first book says: "... He spent his time running on the roads and trails near his home, training for the Boston Marathon." Fixx started running in 1967 at age 35. He weighed 214 pounds and smoked two packs of cigarettes per day. Ten years later, when his book, The Complete Book of Running was published, he was 60 pounds lighter and smoke-free. In his books and on television talk shows, he extolled the benefits of physical exercise and how it considerably increased the average life expectancy. The cover of his book The Complete Book of Running featured Fixx's muscular legs against a red cover. The book sold over a million copies. In 1980 Fixx wrote a follow-up book titled Jim Fixx's Second Book of Running: The Companion Volume to The Complete Book of Running. In 1982 Fixx published Jackpot!, the story of what happened after the publication of The Complete Book of Running when he experienced the "Great American Fame Machine", becoming richer and more celebrated than he could have imagined.
Death
Fixx died on July 20, 1984 at age 52 of a fulminant heart attack, during his daily run on Vermont Route 15 in Hardwick. The autopsy, conducted by Vermont's chief medical examiner, Dr. Eleanor McQuillen, revealed that atherosclerosis had blocked one coronary artery 95%, a second 85%, and a third 70%. In 1986 exercise physiologistKenneth Cooper published an inventory of the risk factors that might have contributed to Fixx's death. Granted access to his medical records and autopsy, and after interviewing his friends and family, Cooper concluded that Fixx was genetically predisposed - his father died of a heart attack at 43 after a previous one at 35, and Fixx himself had a congenitally enlarged heart - and had an unhealthy life: Fixx was a heavy smoker before beginning running at age 36, had a stressful occupation, had undergone a second divorce, and his weight before he took up running had ballooned to 214 pounds. Medical opinion continues to uphold the link between moderate exercise and longevity.
Legacy
Maximum Sports Performance, published posthumously, discusses the physical and psychological benefits of running and other sports, including increased self-esteem, acquiring a "high" from running, and being able to cope better with pressure and tension. A carved granite monument — a book with an inscription to Jim Fixx from the people of Northeast Scotland — now stands in Hardwick Memorial Park in Hardwick, Vermont.
