The venerable Barcelona Review has posted a fascinating write-up of Haruki Murakami's What I Talk About When I Talk About Running.
Murakami believes in a "fiction toxin" that is generated in the creation of a novel. This toxin must be exorcised through physical exertion. And the man knows running, having finished a number of marathons at right around 3:30. That's pretty much cooking, folks.
This one went on my list, and I look forward to reading it. I certainly can relate to his message. When the body is fit and rested, the mind is free to observe and communicate.
