The Big Five

Across thousands of studies involving very large populations, a handful of unglamorous daily habits keep showing up on the right side of the data: coffee, vitamin D, exercise, nuts, and meditation. None requires a subscription, a gadget, or a fad diet. Most cost almost nothing.

Written with David Fisher, The Big Five walks through the evidence habit by habit, separating what the research actually supports from wishful thinking. It is the book behind this site's Big Five page and one of his most requested talks.
