There are two key advantages of thinking of guns as a public health issue. First of all, it removes some of the emotion from the issue. Secondly it moves the debate to be about evidence; where we can empirically show what works, at what cost.

There is a problem with business leaders and the economics profession where we have celebrated the gains from neoliberal policies whilst only paying lip-service to compensating those left-behind.

Biology doesn't need to be obeyed, but it always needs to be considered. If we discuss gender differences, we cannot act as if biology doesn't exist. We live at a time where a group of people – for ideological reasons – have made it clear that they think we can shove biology aside, that everything is culturally constructed, and we can act like biology doesn't exist. That's not going to work, that's not how the world works.

We have to stop pretending that there's no adversity, or that we can't do anything about the adversity we face. We need to fix the culture of silence and ignorance surrounding bias and adversity.

There will be no cure for cancer until real doctors with real patients in real hospitals can attempt an innovation. The court is primarily interested in the effort made, in the attempt. That is what truly counts.

I took the fact that I felt I wasn't good enough as a challenge. This is where I give some of my early bosses and mentors a lot of credit. They invested their time in my training and development.

One you have to get a unique insight. It starts there. Two, you need to be prepared to devote a lot of energy and commitment.

When assessing any new technology, getting experts to explain and understand the benefits and risks is only one aspect of the debate. We also need to involve the public and other stakeholders in a proper transparent discussion on how the technology will be adopted.

Limiting sleep to just 4-5 hours for one single night will drop levels of critical anti-cancer fighting cells, called natural killer cells, by 70%. That's a rather alarming state of immune deficiency, and it happens after just one night of short sleep.

For thousands of years of human history—let alone pre-history—there was never this sense, so common to us now, of a future likely to be radically different from the present. There was really a sense that humanity had already reached its peak, and so the question wasn't what comes next that's better, but rather how to prevent decline and loss.

Entrepreneurs and investors must make discrete choices, often with quite incomplete information and uncertainty about the future, about which ideas to progress and which to shut down. Financiers rather than markets dictate which projects are realized, as they choose which experiments to attempt, how to interpret the results, and whether to continue or abandon the investment.

A lot of governments and corporations have made pledges to be carbon neutral by 2050 without having any way to do it. They don't know how to do it. They don't have the tools to do it. We have found over 1000 solutions that can help.
