The Elusive Runner's High

The New York Times discusses a new study showing that endorphins do flood the brain after long intense exercise.

Endorphins attach to areas of the brain associated with emotions, in particular the limbic and prefrontal areas. The limbic and prefrontal areas are activated when you see the object of your affection or "when you hear music that gives you a chill of euphoria, like Rachmaninoff’s Piano Concerto No. 3." That is the best description of the runner's high -- that is exactly the feeling.

Best Line: "You could really see the difference after two hours of running. You could see it in their faces."
