You get a raise, and for the first week it feels awesome, but then it doesn't have as much impact as you thought it would. Researchers call this the 'impact bias.'

Coming from the German-speaking part of Belgium, my family history includes both German and Belgian soldiers, highlighting the lose-lose nature of war, which only results in death and misery. Therefore, I believe in investing in multilateralism, seeking common ground rather than emphasizing differences.

Diamonds are a miracle of nature, they are millions of years old, they survived a hazardous journey to the earth's surface and the discovery of them is an exciting moment. To see the rough diamond and then watch it come to life on the polisher's wheel with incredible fire and scintillation is incredibly inspiring.

In space, you can only worry about the things you can control – not the constant low-level simmering danger that you might explode and die. If you worried about that, even a two-week flight would be hell, never mind a 200 day one.

The most common misunderstanding is that the Arctic is just a frozen wilderness with a lot of ice and glaciers and a few polar bears roaming. On the contrary the Arctic is a very diverse part of our planet with multiple resources and economic opportunities, the home for over four million people of different nationalities and diverse ethnic origin.

The heart is a fascinating machine. It beats 3 billion times in a typical human lifetime, consumes so much energy, and does so much work that if you attached a heart to a typical swimming pool – the heart would empty the pool in about a week.

Every person is different, but every sale is the same.

I do believe there's something fundamentally essential about free play—the open-ended combination of elements not confined by a narrow context. This concept is vital not only to humanity but to life itself.

Race and guns, both of which have conspired not only to take the life of a teenager, but to make that killing entirely permissible. I can't look an African-American parent in the eye for thinking about what they must tell their sons about what can happen to them on the streets of their country.

In the spring, when we lose an hour of sleep, we observe a consequential 24% increase in heart attacks the following day. In the Autumn, when we gain an hour, we see a corresponding 21% reduction in heart attacks. It's a clear bi-directional relationship.

Much of the pushback against science is related to a distrust of the establishment and of multinational corporations and their profit motive. It's easy to spread fear; as humans we're very tuned and sensitive to it.

When I approach anything, especially high-risk activities, I always brace myself for the worst outcome – death. By accepting death, they rid themselves of the fear and could focus purely on survival. This mentality is my cornerstone.
