Salman Abedi, Khalid Masood, Khuram Butt, all of these people and the people in ISIS, Al Qaeda, Boko Haram, Al-Shabaab… We tend to think sometimes that they are extremism. But the reality is they didn't breed extremism. Islamist extremism bred them.

Ultimately, I think we'll be able to pop a pill and reset our body's age. It takes us about 4-8 weeks currently to reset the age of a mouse, it shouldn't be any different for humans.

You must surround yourself with great people, and as you grow, never forget the generosity gene. You must demonstrate that gene with encouragement, praise, recognition, and cash... Building a great team is what this business game is all about. The team with the best players working together wins.

My understanding of humanity was changed more by working in the space industry than space travel itself. It opened up my eyes to what international collaboration can really achieve. The space industry and scientific community seem to transcend all that. You realise that you're involved in this incredible international space station that's been occupied for 20 years and which simply couldn't have succeeded if it wasn't for everyone collaborating together.

These new regulations should (in theory, although there is no research to test it) prevent this psychological risk aversion by ensuring that all counterparties know that at a wholesale and institutional level, they are safe.

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've found that innovation really happens when you constrain a problem very specifically and then throw it out to the world to solve. It's a slightly different way of thinking.

Choices are like train tracks – the train go where the tracks take them – we go where our choices take-us. Our lives are a reflection of the poor, and the positive, life choices we've made (and make!).

Comedy delivers the cerebral and the hyperbole, it can be funny and serious. You can see that ability for the pendulum to swing both ways when you watch the best comedians perform.

Our news outlets could report the fact that 137,000 people escaped from extreme poverty yesterday, every day for the past 30 years – but they never ran that headline, with the result that over a billion people escaped poverty and nobody knows about it.

We even regulate toy guns, by requiring orange tips — but lawmakers don't have the gumption to stand up to National Rifle Association extremists and regulate real guns as carefully as we do toys.

I believe that making players conform to a rigid system would lead to the loss of many potentially great talents, with only a handful thriving. Out of respect for the players, I opted for a different approach – selecting fewer players but offering highly personalized training.
