Jo Piazza was working as a travel editor when she met a man, married him— and spent the next year traveling to dozens of countries together, asking how marriage works in each place. She visits Sex Lives to revisit what she learned from women in Chile, Israel, Tanzania, India, France, Denmark, and beyond— and why, after discovering that she had a genetic mutation associated with muscular dystrophy, she climbed Mt. Kilimanjaro with her husband. (And competed in a rare Finnish sport called "wife-carrying.") Piazza's book, "How to be Married: What I Learned from Real Women on Five Continents About Surviving My First (Really Hard) Year of Marriage," is in bookstores now. With Maureen O'Connor.
