Alzheimer's starts its destructive process 30 years prior to its typical diagnosis. If we were to compare this to our approach with heart disease, it's like only making a diagnosis when a coronary bypass is needed.

Over this 99.9% of human existence, when technology advances, population advances and counterbalances any potential increase in human prosperity. Suddenly once technological progress reaches a tipping point, families start to invest in education, they economise on the number of children, and technological progress is converted into richer people rather than into more people.

Once the cancer of authoritarianism gets into the veins and organs of society, it's not easy to get-out – they have this very specific way of paralysing political mechanisms and dismantling the fundamental human logic.

Champions possess a distinct mindset, a relentless drive for excellence that sets them apart. They're not content with just doing okay; they strive for excellence constantly. Being second is not an option for them, they aim for the top.

One of the sources of overconfidence in our ability to forecast the future is the great ease with which we find explanations for the past. That's a very significant mechanism that produces overconfidence.

Revolution was, in a way, the original problem of political thought. Constitutionalism is a Greek answer to the problem of revolution. You want to avoid revolution? Then you need to design a constitution in a certain way—so that it's balanced and less likely to be overturned by revolution.

Ultimately, you have to fail at some stage with whatever you do, to get the successes that you need in the end.

Today, policies are sold to us largely on the basis of fear, or fear mitigation: from immigration to climate change, from health services to defence. It's less about promoting a progressive vision of the future and more about playing to our fears of what might happen if we don't toe a particular line.

Even if you're eating right, exercising regularly, and getting enough sleep, dysfunctional breathing can still hold you back. If it's dysfunctional, your body will eventually make you pay the price in terms of health and focus.

We flee from affliction the way an animal flees from death. There's a sense in which it's perfectly natural that our response to difficulty in life is aversive. We're only going to be able to live well with the difficulties of life if we face up to them, because they're difficult.

At a point, we developed language sophisticated enough to transmit abstract ideas with precision from one mind to another. That enables high quality parallel processing of problems such that we literally have emergent cognition. When people gather, they talk about difficult puzzles they face, and the product of their thinking exceeds the sum of their individual capacity to reason through it.

Looking at the bond market to provide you protection from inflation is a fools game. If you are really worried about inflation- you have to buy stocks.
