Our ancestors had to eat whenever food was around. And we're actually still hardwired the same way. The big difference is we don't have to hunt for our food. For us, "hunting" comes down to sliding the milk carton out of the way.

It's a big issue for me - feeling like I should be helping every person who asks for something or who has a problem.

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.

I do practice what I preach when it comes to nutrition.

I used to bicycle to work across the George Washington Bridge, but my wife told me it wasn't professional.

I get up at the same time every morning.

I'm sure people think that I'm out in left field you know, playing by myself.
