A batch of the best highlights from what Todd's read, .

I believe the reason that animals on a low-calorie diet live longer is that there is a cost to putting on fat. The food we eat is either broken down into immediate energy (which we call adenosine triphosphate, or ATP) or turned into stored energy (such as fat). Usually the calories we eat are turned into immediately available ATP. To instead store these calories for later, our cells must reduce the production of ATP and divert the excess calories to fat. Our research group determined that this is done through exposing the cells’ “energy factories” (also known as mitochondria), where most of the ATP is produced, to a phenomenon called oxidative stress. Thus, the cost of storing fat is some oxidative stress to our energy factories. If sustained for decades, this stress can lead to reduced function in—and even the loss of—these factories, which are responsible for the energy we need to maintain our bodies at full throttle.

John Foster Dulles: “The measure of success is not whether you have a tough problem to deal with, but whether it is the same problem you had last year.”

The press secretary makes *claims*; the board makes *bets*. …A __bet__ is any decision in which you stand to gain or lose something of value, based on the outcome. That could include money, health, time—or reputation….So when you're thinking about how sure you are, your answer will be more honest if you switch from thinking in terms of "What can I get away with claiming to myself?" to __“How would I bet, if there was something at stake?"__
