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.

Marianne Legato: My name is Dr. Marianne J. Legato. I’m a professor of clinical medicine at Columbia University.

Question: Are men more prone to diseases?

Marianne Legato: In spite of their obvious increased physical strength compared to women, men are more vulnerable biologically than women are. The vulnerability begins in the womb. Far fewer male embryos make it to delivery compared with females. Even at birth, boys are developmentally behind their sisters and are prey to developmental disabilities and respiratory problems among others in the weeks immediately after birth. This vulnerability continues during the course of their life. One of the most important health problems of men is the early onset of coronary artery disease which begins to be symptomatic in many men in the mid thirties. And those men who have coronary disease are usually dead before the age of sixty-five. I think this is one of the most compelling health problems that men face and something on which we should really be concentrating.

Question: Are men also more prone to developmental disabilities?

Marianne Legato: Developmental disabilities are four to six times more frequent in males than in females. We don’t really know why this is correct but a very interesting theory has developed in which it was pointed out by some neo-natal experts. That the brains of boys are larger than those of their sisters and at the same time their metabolic rate is lower so that the demands of the bigger brain are really not met as efficiently by the low metabolic rate which doesn’t deliver enough oxygen and blood to the brain as is the case with their sisters who have smaller and probably more efficient systems of providing the brain with blood and oxygen.

Question: Is there an age where men are particularly vulnerable?

Marianne Legato: One of the most vulnerable periods for men, or males, is during adolescence. There is a lag time in the development in the systems in the brain that have to do with risk assessment and judgment. At the same time, the surge of testosterone makes them prone to idealistic, impulsive and risk-taking behavior so that suicide and violent death is far more common in the male adolescent than it is in the female adolescent. We really capitalize on this, sadly, by sending eighteen year olds to war. A very smart man had said to me, who was in the military, that if you ask an 18 year old to take a well-defended objective, he’ll say “when?” If you ask a thirty-year-old to take the same objective, he’ll say “how?” And if you ask a forty-year-old man, he’ll say “why?”

Question: What steps should we be taking to help men lead healthier lives?

Marianne Legato: I think there are definite steps we should be taking, and taking immediately, to ensure better and longer lives for men. In the first place, we should stop regarding them as the “stronger sex.” They’re biologically much less hardy in many ways than are women. In particular, we should be concentrating, in my opinion, on the early onset of coronary disease which takes such a terrible toll of men. And I think the American Heart Association should have a program called Go Blue for men, the way it does Go Red for women. I think heart disease in its early and devastating onset in men is one of the most important health problems that we face.
