Fixx was a member of the high-IQ club, Mensa,[3] 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 (97 kg) and smoked two packs of cigarettes per day. Ten years later, when his book, The Complete Book of Running (which spent 11 weeks at number one on The New York Times Best Seller list) was published, he was 60 pounds (27 kg) 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.
Fixx died on July 20, 1984, at age 52 of a heart attack, during his daily run on Vermont Route 15 in Hardwick.[1] 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%.[4][5]
