Those who usually frowned in photos when they were children and teenagers are five times more likely to get divorced later in life than those who smiled in their photos. The more intensely you smiled in childhood photos, the less likely that you’ll divorce later in life. (I’ll bet parents are going to examine their kids’ photos, reading this.)
Also smiling for photos does not necessarily cause a good marriage, yet bright smiling and an enduring marriage are somehow connected.
Looking back at my childhood photos I often had a mild smile and that deer in headlights look. Without seeing the photos Matt conjectured that might rate me a 5 out of 10. In other words smack dab in the middle of the “smile intensity scale.” And I am divorced.
