Living in the now also fits with the fact that the Pirahã don't appear to have a creation myth explaining existence. When asked, they simply reply: "Everything is the same, things always are." The mothers also don't tell their children fairy tales -- actually nobody tells any kind of stories. No one paints and there is no art.
Even the names the villagers give to their children aren't particularly imaginative. Often they are named after other members of the tribe which whom they share similar traits. Whatever isn't important in the present is quickly forgotten by the Pirahã. "Very few can remember the names of all four grandparents," says Everett.
