You've been at it so long, you've forgotten what it's like to work hard for something.

So I thought this time I should maybe ask him because he's stopped asking me.

I'm about providing the means to build something that will grow and intensify its original investment and not just require greater giving next year -- I'm not trying to feed the habit.

And I started putting the first YouTube videos up, really just as a kind of nice-to-have, just kind of a supplement for my cousins, something that might give them a refresher or something.

I use spoken word to help my students rediscover wonder, to fight their instincts to be cool and unfazed and, instead, actively pursue being engaged with what goes on around them, so that they can reinterpret and create something from it.

That its transition from being something that we extract and derive from the world to something that actually starts to shape it -- the world around us and the world inside us.

So we did some experiments where we saturated our poor patients with zillions of electrodes and then had them try to do two dozen different tasks -- from wiggling a finger to moving a whole arm to reaching for something -- and recorded this data.

So if I want the music to get to a certain level of intensity, the first step for me is to be patient, to listen to what's going on and pull from something that's going on around me.

The redefined physician is human, knows she's human, accepts it, isn't proud of making mistakes, but strives to learn one thing from what happened that she can teach to somebody else.

We're sort of on this line in a transition from the way the world used to be to some new way that the world is.

If we could raid the annals of 100 years of film, maybe we could build a narrative that would deliver meaning to the fragmented and restless world of the young.

But he was the second child, and the level of supervision had plummeted. (Laughter) So he wandered in, and it imprinted on him like a mommy duck does to its duckling, and I don't think he understands what's going on, but he is sure soaking in it.

We see this general bagginess of the structure, the lack of concern with rules and the way that we're used to learning on the blackboard, and so we think that something has gone wrong.

It takes practice to become a good arguer, in the sense of being able to benefit from losing, but fortunately, I've had many, many colleagues who have been willing to step up and provide that practice for me.

The digital world cannibalizes time, and in doing so, I want to suggest that what it threatens is the completeness of ourselves.

She said, "There's one room in my new place for the boys and one room for the girls, but at night, they're just all up on my bed, and we're doing homework all together and everything.

And I say, absolutely, and for me, that's success, because as a scientist, my goal is not to infer information about users, it's to improve the way people interact online.

I can hear something that I love in a piece of media and I can co-opt it and insert myself in that narrative, or alter it, even.

That's war too, is a lieutenant saying, "Please make something happen because we're going crazy."

And if the Internet doesn't like it when you try to remove things from it, just watch what happens when you try to shut the Internet down.

So in our lab, we're trying to understand these factors better, and many other groups are trying to understand, what are the true aging factors, and can we learn something about them to possibly predict age-related diseases?

Ants may not be able to vote, hold meetings or even make any plans, but we humans may still be able to learn something from the way that such simple creatures are able to function so effectively in such complex ways.

(Laughter) Then -- (Laughter) Then we're going to go over to the fridge, to see if there's anything new in there since 10 minutes ago.

So a few years ago I decided, well, I'm a journalist, I should see if I can do any better by going around the world and actually asking folks if and how they've tackled their big economic and political challenges.

If we've learned anything from our previous history, it's that yes, we gain the power to manipulate, but because we didn't really understand the complexity of the ecological system, we are now facing an ecological meltdown.

(Laughter) And, you know, I wrote a book. So I'll say something -- (Laughter) -- I'll say a little about, you know, how the discovery was made, and why Francis and I found it.

Ultimately, we want to get to a metric where people can tell us, "Hey, I learned something from Twitter, and I'm walking away with something valuable."

I thought that something would come out of it, like "Words rule fantastic new old first last Pope" because it's by Alexander Pope, but I sort of made a mess out of it, and then I thought I'd repeat it in some way so it was legible.

We read some of the 82, 000 comments that were made during the video, and we hypothesized that they were excited because they were participating in the shared anticipation of something that was about to happen.

This was, at a distance, realizing that someone was feeling something, wanting to affect them in a particular way, using media to do it, putting it online and realizing that there was a greater impact.

She went through many months of harsh chemotherapy and painful surgeries, and then just as she was ready to jump back into the dating world, she found a lump in her other breast and had to do it all over again.
