We are out of touch. Many people fear that we are trapped inside our screens, becoming less in tune with our bodies and losing our connection to the physical world. But the sense of touch has been undervalued since long before the days of digital isolation. How to Feel explores the scientific, physical, emotional, and cultural aspects of touch, reconnecting us to what is arguably our most important sense. Sushma Subramanian introduces listeners to the scientists whose groundbreaking research is underscoring the role of touch in our lives.

Over millions of years, male and female bodies developed crucial physiological differences to improve the chances for human survival. These differences have become culturally obsolete with the overturning of traditional gender roles. But they are nevertheless very real, and they go well beyond the obvious sexual and reproductive variances: Men and women differ in terms of digestion, which affects the way medications are absorbed. Sensitivity to pain is dependent on gender.

We inherit mechanisms for survival from our primeval past - none so obviously as those involved in reproduction. The hormone testosterone underlies the organization of activation of masculinity: It changes the body and brain to make a male. It is involved not only in sexuality but in driving aggression, competitiveness, risk-taking - all elements that were needed for successful survival and reproduction in the past. But these ancient systems are carried forward into a modern world.

This is the audio summary of Head Strong, a book that takes a deep-dive into some of the latest findings from the world of neuroscience, all in an effort to teach us how to boost brain performance.
