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.

Almost Everyone Needs to Take Vitamins

September 8, 2013, 6:00 AM

I think you don't need vitamins only under certain conditions. 

Only if you eat pure wild food, drink pure clean water, are exposed to no environmental toxins, sleep nine hours a night, have no stress and only have wild foods that you harvest yourself. 

Now, I don't know how many people that describes in the modern world, probably not that many.  The rest of us do need a good multivitamin, we need fish oil and we need vitamin D, because those will cover the bases for most of the nutritional deficiencies we see in up to 90 percent of the population.
