When you consider it from a human perspective, and clearly it would be difficult for us to do otherwise, life is an odd thing. It couldn't wait to get going, but then, having gotten going, it seemed in very little hurry to move on.

But I got a great deal else from the experience. I learned to pitch a tent and sleep beneath the stars. For a brief, proud period I was slender and fit. I gained a profound respect for the wilderness and nature and the benign dark power of woods. I understand now, in a way I never did before, the colossal scale of the world. I found patience and fortitude that I didn't know I had. I discovered an America that millions of people scarcely know exists. I made a friend. I came home.

Black bears rarely attack. But here's the thing. Sometimes they do. All bears are agile, cunning and immensely strong, and they are always hungry. If they want to kill you and eat you, they can, and pretty much whenever they want. That doesn't happen often, but - and here is the absolutely salient point - once would be enough.

Germans are flummoxed by humor, the Swiss have no concept of fun, the Spanish think there is nothing at all ridiculous about eating dinner at midnight, and the Italians should never, ever have been let in on the invention of the motor car.

I tell the kids that, even in a childhood marked by despair and deprivation, I knew that no matter what happened, I still had my family, or at least the remnants of a family ripped apart by divorce and then glued back together in various odd arrangements through a series of ill- advised remarriages. It was good to know I had a solid foundation.

I understand cricket - what's going on, the scoring - but I can't understand why.

Every living thing is an elaboration of a single original plan. As humans we are mere increments - each of us a musty archive of adjustments, adaptations, modifications and providential tinkerings stretching back to 3,8 billion years. Remarkably we are even quite closely related to fruit and vegetables. About half the chemical functions that take place in a banana are fundamentally the same as the chemical functions that place in you. It cannot be said too often: all life is one. That is, and I suspect will ever prove to be, the most profound true statement there is.
