When people know they are being photographed, they tighten their emotions. Wait long enough, perhaps on the seventh inhale or the unexpected yawn, and you can often catch a glimpse of their hearts by watching their eyes. On a mountain in Bhutan and a desert in India, there are mothers and fathers pondering the future of their sons and daughters. On an iceberg in Antarctica, there is a bird contemplating the danger of a world dressed in white. In classrooms around the world, there are teachers and students searching for an answer to the same question: What will happen next?
Pondering. Life would be so expressionless without it.
