“Both you and the meeting attendees are falling prey to an evolutionarily imprinted lull in wakefulness that favors an afternoon nap, called the post-prandial alertness dip (from the Latin prandium, “meal”). This brief descent from high-degree wakefulness to low-level alertness reflects an innate drive to be asleep and napping in the afternoon, and not working. It appears to be a normal part of the daily rhythm of life. Should you ever have to give a presentation at work, for your own sake—and that of the conscious state of your listeners—if you can, avoid the midafternoon slot.”

“This transformation started by the iPod, however, didn’t reach its full potential until the release of its successor, the iPhone, or, more generally, the spread of modern internet-connected smartphones in the second decade of the twenty-first century. Even though iPods became ubiquitous, there were still moments in which it was either too much trouble to slip in the earbuds (think: waiting to be called into a meeting), or it might be socially awkward to do so (think: sitting bored during a slow hymn at a church service). The smartphone provided a new technique to banish these remaining slivers of solitude: the quick glance. At the slightest hint of boredom, you can now surreptitiously glance at any number of apps or mobile-adapted websites that have been optimized to provide you an immediate and satisfying dose of input from other minds.”

“Things get even more interesting when birds group together. In some species, many of the birds in a flock will sleep with both halves of the brain at the same time. How do they remain safe from threat? The answer is truly ingenious. The flock will first line up in a row. With the exception of the birds at each end of the line, the rest of the group will allow both halves of the brain to indulge in sleep. Those at the far left and right ends of the row aren’t so lucky. They will enter deep sleep with just one half of the brain (opposing in each), leaving the corresponding left and right eye of each bird wide open. In doing so, they provide full panoramic threat detection for the entire group, maximizing the total number of brain halves that can sleep within the flock. At some point, the two end-guards will stand up, rotate 180 degrees, and sit back down, allowing the other side of their respective brains to enter deep sleep.”

“During Dorabji’s leadership, three hydroelectric power companies, two cement companies, a large edible oil and soap company, an insurance company and an airline were added to the Tata group. Dorabji’s role in building the Tata empire is often glossed over, perhaps because he was overshadowed by two particularly charismatic individuals—his predecessor Jamsetji and his successor JRD.”
