What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

The Longevity Revolution

The Big Idea for Saturday, August 09, 2014

In 1970, life expectancy in the U.S. was 70 years old; today it's around 78. In China, over 40 years ago, the life expectancy was around 62, and now it's around 73 years old. Why are we living longer? That's been the trend over the course of human history. But reports in the U.S., for example, say that life expectancy is slowing its climb due to high obesity rates and smoking.

Doctors today can perform cutting-edge treatments to help us live longer, but the breakthroughs of science alone can help us live full and healthy lives. Today's big idea explores the longevity revolution, and eating your way to a better life.
