At the end of the day, sleep is a barometer of your emotional health. And so if you're not in the right place where you need to be, then you're going to have voices keeping you up at night because you have to work through those issues.

If I make your workplace conducive to walking at lunch, or working out at some time during the day, or I get people to use the stairs more by creating incentives to do such, then people will start doing it naturally.

One way to fuel the brain to make more decisions is to feed it carbs. So as the day goes on, you start to crave more carbs - especially women, because women tend to make more of the day-to-day decisions in our lives than men.

Whatever you choose, do it fully-with passion and childlike enthusiasm.

When there is a psyche-disrupting event in your life, it can prevent you from getting the long blocks of sleep at night that are so important to healthy aging.

Food is no longer sacred to us: in becoming too efficient we've changed its nature.
