author and researcher Scott Barry Kaufman (no relation to Ed), who taught a popular course on positive psychology and gratitude at the University of Pennsylvania. I wanted a little background on the science of thankfulness. “Gratitude has a lot to do with holding on to a moment as strongly as possible,” Scott told me. “It’s closely related to mindfulness and savoring. Gratitude can shift our perception of time and slow it down. It can make our life’s petty annoyances dissolve away, at least for a moment.”
