As two adversaries accumulate a longer history of conflict, their rivalry relationship tends to become 'locked-in' or entrenched, with future conflict becoming increasingly difficult to avoid; characteristics of their past confrontations can hasten or reverse this movement toward rivalry.

People like to compare such rare payoffs to lottery tickets. This is way off. We know from the availability heuristic that people overestimate the likelihood of an event based on their ability to envision it—the risk of plane crash versus car crash is the best example of this.

In the case of Brazil, one of the most important things is the huge ethnic and cultural mixture which makes us a country with dynamism, vibrancy, and the ability to understand the psychology of other nations.

When I have a bad day, that has nothing to do with the market! But how I respond to that bad day may be a reflection of a general level of discomfort about how the economy is doing and so forth. It's an out-of-bounds signal. In that sense, it's pretty unique!

What's special about it as a science subject is that it is so awkward, it doesn't lend itself to easy solutions. It's a multi-factorial problem, very different to- for example- the question of what causes influenza?

We make ourselves miserable, or we make ourselves happy. The amount of work is the same…

The awareness of life as being finite allows them (somewhat counter-intuitively) to live… This doesn't necessarily mean being reckless, but rather that they engage in activities which are positive for their well-being- things like travel, education, spending time with family and friends, and so on.
