That’s up to 1,200 times per hour and a whopping 28,800 times in a day —much more often than we need to keep our eyeballs lubricated.

When our brains aren’t concentrated on a task, brain regions known as the “default mode network” come alive, allowing our mind to switch into an idle mode—a phenomenon researchers discovered decades ago.
