concerns on the medicalization of bereavement by harvard psychiatrist, anthropologist and widower Arthur Kleinman in thelancet

“My grief, like that of millions of others, signalled the loss of something truly vital in my life. This pain was part of the remembering and maybe also the remaking. It punctuated the end of a time and a form of living, and marked the transition to a new time and a different way of living. The suffering pushed me out of my ordinary day-to-day existence and called into question the meanings and values that animated our life.”

When something threatens your life, this area seems to kick into overdrive, recording every last detail of the experience. The more detailed the memory, the longer the moment seems to last. “This explains why we think that time speeds up when we grow older,” Eagleman said—why childhood summers seem to go on forever, while old age slips by while we’re dozing. The more familiar the world becomes, the less information your brain writes down, and the more quickly time seems to pass.
