So that's the vision that I've been thinking about.

And one of the things that I've been thinking about recently is what is worth while.

And I've been thinking about how that applies across a whole spectrum of realms, from, say, the ecological, okay.

I've spent the past year thinking about what it really should be about.

They've been sitting on my shoulder the whole time while I've been thinking.

I've been spending a lot of time thinking about coffeehouses for the last five years, because I've been kind of on this quest to investigate this question of where good ideas come from.

Now I've been influenced in this thinking by two anecdotes that I want to share with you.

In other words, as you heard Chris say, I've spent the last five years thinking about being wrong.

At this ripe old age of 30, I've been thinking a lot about what it means to grow up in this horrible, beautiful time, and I've decided, for me, it's been a real journey and paradox.

Because if you spend this week thinking about Iraq and thinking about Bush and thinking about the stock market, you're going to miss one of the greatest adventures that we've ever been on.

So, up until now I've been talking to you about really large numbers.

I'm thinking about you.

I'm thinking about you.

I've always been very worried about resource.

Yeah, I've been worrying about that too.

Gets you thinking about color.

What are you thinking about?

I've been doing that for about 10 years.

I've been working with him about 10 years.

I've been wondering for a long time, since I've been thinking about memes a lot, is there a difference between the memes that we copy the words we speak to each other, the gestures we copy, the human things and all these technological things around us?

This past year I've been in Latin America, I've been in China, talking about the fundamentals of laparoscopic surgery.

But I realized that life could be very boring, so I've been thinking about life, and I notice that my camera my digital camera versus my car, a very strange thing.

Why do you think I'm thinking about you?

And so, as I have been thinking about this, I've been wondering how can we engage these supportive communities to catalyze even more entrepreneurial ideas and to catalyze all of us to make tomorrow better than today?

Are you seriously thinking about not going?

I've been looking for you.

I've been talking about getting more from less for more.

I've been banging on about this like I can't believe.

I've been carrying on here about the biology of love.

So I've been talking about this, suggesting, perhaps, that mind wandering causes unhappiness, but all I've really shown you is that these two things are correlated.

So I have been thinking about this question a lot lately.

Why do you think that I'm thinking about you?

He said, Everything I've been telling you for the last 20 years, forget about it. It was wrong.

And I've always been nervous about the term futurist, because you seem doomed to failure because you can't really predict it.

I've been making these forward looking predictions for about 30 years.

You can't stop thinking about another human being.

Because what I've been doing for the last four years, really since the first time you saw me some of you saw me at TED when I was talking about religion, and in the last four years I've been working just about non stop on this topic.

I've been wanting to see you.

I've been requested to help you.

I've always been proud of you.

I've always been proud of you.

Where have you been? I've been to the barber's.

It's actually very basic stuff thinking about continuity, thinking about backups, thinking about the things that actually matter.

What are you feeling and thinking about this photo, about this woman?

Now, finally, I've talked to you about food, and I've talked to you about cancer, so there's just one more disease that I have to tell you about and that's obesity.
