We found this--and its author--monomaniacal: ""If I am in a group and not talking,"" says this Runner's World columnist/cardiologist/racer, ""do not suppose I am listening. . . I am off in another world. Off in my natural habitat, my mind."" If you can wade through statements like that and platitudes like this""If you are seeking the solutions for the Great Whys of your creation you will have to start with the Little Hows of your day to day living""--to get to the Magic Six (exercises that develop runner's muscles) you might obtain some useful information about this year's fad sport. Racing tips for the aged runner: ""I make my breathing as quiet as possible, my footstrike almost unheard, and I pass them swiftly and with elan, exuding confidence."" Which should not be hard for him. This best-selling author's well-conditioned lungs are full of hot air.
