Using Smartphone Cameras to Track Alertness
"Cornell researchers have developed a tool that tracks alertness by measuring pupil size, captured through a burst of photographs taken every time users unlock their smartphones.
...
"When people are alert, the sympathetic nervous system causes the pupils to dilate to make it easier to take in information. When they're drowsy, the parasympathetic nervous system causes the pupils to contract.
...
"the AlertnessScanner could be particularly useful in health care, since medical professionals often work long hours doing intricate and important work. For example, clinicians typically look at devices during surgery, and a front-facing camera on the devices could track their alertness throughout procedures.

"But understanding alertness patterns could be helpful to people in many kinds of workplaces, Tseng said.

"If you want to get something very important done, then probably you should execute this task while you're at the peak of your alertness; when you're in a valley of your alertness, you can do something like rote work," he said. "You'll also know the best time to take a break in order to allow your alertness or energy to go back up again."

The Bezos way: sleep, puttering, and three high-quality decisions a day
“He likes to do his “high IQ” meetings before lunch because that’s when he’s sharpest, and he knows by 5pm he’ll be wiped. Anything that’s important that pushes late into the day gets rescheduled for 10 a.m. the next day. He recognizes that he “only” needs to make a few key decisions a day, not thousands of small ones. If he can make three high quality decisions a day, that’s plenty good.”
