"I Have a Question!"  [58:48]

Today's questions:

"James: Could the research on the impact of shift-work on health be applicable to the impact of Ramadan?"

"Nick: I would be interested to hear your thoughts about how certain types of occupations can create barriers to better diets and lifestyles. For example, I have several friends who are long-haul truckers who frequently cross the border between Canada and the United States. Many healthy foods, like fresh produce, cannot legally cross the border. This leaves these people dependent on packaged, processed junk foods that they acquire from truck stops and gas stations. Sometimes for weeks on end. It's heartbreaking because they are fully aware of what a healthy diet is, but their job just makes it impossible for them to integrate a healthy diet into their lives. How in the world do we fix stuff like this?"

Ideas about "optimizing" and "hacking sleep. And the idea that sleep debt can never be repaid.
