This book lets you match wits with master problem solvers in a fascinating collection of math, logic, and word puzzles that at first glance may seem impossible to solve.
James Fuller Fixx was the author of the 1977 best-selling book, The Complete Book of Running. Best known as Jim Fixx, he is credited with helping start America's fitness revolution, popularizing the sport of running and demonstrating the health benefits of regular jogging.
I've had this book and it's companion "Games for the Super Intelligent" since high school. Always fun to come back and see what piques my interest years later.
