In the future, these blood tests will allow us to offer treatments for Alzheimer's disease 10, 20, or even 30 years before symptoms start to manifest, much like how we currently handle cholesterol. This early detection and intervention will be our strategy for combating Alzheimer's.

If you think of a candle- it's bright, but the light goes out in all directions, like a sphere. If you think of a laser beam- the light is concentrated in one direction, and it can be much more powerful than a candle. Goals focus our energy in the same way.

Adversity is happening all around us at the individual level, it's happening at a company level, it's happening at industry levels; and we can either face it and learn from it or we can pretend it's not happening. And I think that is the key.

Technology is no longer a separate segment- it is pervasive. It is technology IN agriculture, IN governance, IN education, IN health. It is also about health technologies, education technologies and agricultural technologies- there are two sides to it.

The general body of research suggests a moderate positive correlation between religiosity and happiness. Religion provides a sense of community and cohesion within an in-group. It draws clear lines between in-group members, with whom I can engage in cooperative behaviour and reciprocal exchanges, and out-group members. Religion also offers purpose and meaning through a supernatural narrative.

Success is different for everyone, but for me success has always been about finding meaning and personal fulfillment. If I can wake up every day, feel engaged in my work and know that I tried my best to help others feel the same as me, then I feel successful.

White people have nothing to fear from understanding their history- they're not responsible for it. It's like having therapy… it's understanding our past behaviours so that we don't repeat them. I think we need to face up to our imperial history for the same reasons.

For me it is extremely important that commercial interests and social benefits are not mutually exclusive, but that they can complement each other wonderfully so I always look out for products that are innovative, forward-thinking and offer a true value for society.

Being an entrepreneur, an inventor, is about having ideas and having the doggedness to see them through… As an inventor your ideas should be based on creating a solution to a problem – a solution which focuses on function over form. Solving problems has been my life's work.

We define the credit risk of a bond portfolio as the volatility of the CDS basket which would perfectly hedge the sovereign risk of the portfolio.

I found myself transitioning from an extremely short-term world into an environment where the focus was primarily long-term. The environment, based around colleges, was more relaxed and unhurried. The pace was different – no hourly targets here – with a collegiate atmosphere that placed greater importance on future implications.

Humans began to create and believe things that exist only in their own imagination. Things such as gods, nations, money and human rights. This enabled humans to start cooperating on an unprecedented scale.
