I tried the paleo diet, which is the caveman diet - lots of meat. And I tried the calorie restriction diet: The idea is that if you eat very, very little - if you're on the verge of starvation, you will live a very long time, whether or not you want to, of course.
I don't know what leadership is. You can't touch it. You can't feel it. It's not tangible. But I do know this: you recognize it when you see it.
