Our apps and platforms are addictive by design. We know this both because the tech titans behind them have admitted it publicly, and because the dominant apps and social media platforms use the same suite of techniques that are well-proven to ensnare us.

I don't think you can find any other organ in the body that has correlation with so many other organs than the mouth. Research has been widespread, and over the past 30 years, gum disease has been linked to heart disease, to colorectal cancer, to diabetes, to all sorts of issues within the body.

More than one hundred million have been uprooted in the first eighty years of the twentieth century- millions permanently displaced as a result of revolutions, division of countries, annexations or boundary changes and other territorial arrangements. The political refugee has become the symbol of worldwide political and social change.

If you go to any rave, or any football event, you will find people chanting in a rhythm- human beings do that. We have this sense to participate and organise- Music lets you rediscover your humanity, and your connection to humanity. When you listen to Mozart with other people, you feel that somehow- we're all in this together….

If you look at the balance sheets of Fortune 500 companies 50 years ago and today, 50 years ago, 80% of the value was physical stuff. Today, more than 85% of the value consists of intangibles. Companies must become so much more now that their value comes from their ability to inspire, drive and organise human beings.

The fact that you and I are alive is against stupendous odds. One day we will die, and that's sad, but there are people who will never die because they were never born. We're the lucky ones, we get to die. You can only die if you were alive.
