How does Dan Brown work? Here's what he says on his personal website:
If I'm not at my desk by 4:00 A.M., I feel like I'm missing my most productive hours. In addition to starting early, I keep an antique hour glass on my desk and every hour break briefly to do pushups, sit-ups, and some quick stretches. I find this helps keep the blood (and ideas) flowing. I'm also a big fan of gravity boots. Hanging upside down seems to help me solve plot challenges by shifting my entire perspective.For more on the controversy surrounding 'The Da Vinci Code,' there are articles on the BBC website, and the Guardian.
