Recently I read a survey done by a doctor who cited the happiest people on earth. Near the top of the list was a group of Christians called Seventh-day Adventists, who are religious, literally, about the Sabbath. This doctor noted that they lived ten years longer than the average American.19 I did the math: if I Sabbath every seven days, it adds up to—wait for it—ten years over a lifetime. Almost exactly.
