137. Marta Zaraska — Growing Young: How Friendship, Optimism, and Kindness Can Help You Live to 100

137. Marta Zaraska — Growing Young: How Friendship, Optimism, and Kindness Can Help You Live to 100

From the day her daughter was born, science journalist Marta Zaraska fretted about what she and her family were eating. She fasted, considered adopting the keto diet, and ran a half-marathon. She bought goji berries and chia seeds and ate organic food. But then her research brought her to read countless scientific papers and to interview dozens of experts in various fields of study, including molecular biochemistry, epidemiology and neuroscience. What Marta discovered shattered her long-held beliefs about aging and longevity. A strong support network of family and friends, she learned, lowers mortality risk by about 45 percent, while exercise only lowers it by about 23 percent. Volunteering your free time lowers it by 22 percent or so, while certain health fads like turmeric haven’t been shown to help at all. These revelations led Marta Zaraska to a simple conclusion: In addition to healthy nutrition and physical activity, deepening friendships, practicing empathy and contemplating your purpose in life can improve your lifespan. Shermer and Zaraska also discuss:

  • diet, nutrition, and supplements: what works, what doesn’t, and what about meat?
  • exercise: how much, what type, and when?
  • the causal mechanisms behind how relationships and marriage effect health,
  • how friendships and community affect longevity,
  • how religion makes people healthier and longer lived,
  • why we need others and why handshakes and hugs will return after COVID-19,
  • the harmful effects of loneliness and isolation,
  • the deleterious effects of stress, and
  • how leading a purposeful and meaningful life leads to longevity.

Marta Zaraska is a Canadian-Polish science journalist. She has written about nutrition and psychology for the Washington Post, Scientific American, The Atlantic, The Los Angeles Times, New Scientist, and several other publications. She is the author of Meathooked: The History and Science of Our 2.5-Million-Year Obsession with Meat (Basic Books, 2016), which has been translated into Japanese, Korean, simplified Chinese, Spanish and Polish, and chosen by the journal Nature as one of “the best science picks” in March 2016. Meathookedhas also been praised in The Wall Street Journal, Discover Magazine, Time, The Washington Post, Kirkus Reviews, Natural History Magazine, etc. She has also contributed a chapter to the recently published The Reducetarian Solution (TarcherPerigee, 2017) alongside Mark Bittman, Michael Shermer, and Peter Singer.

What Einstein Meant by God: Science, Spirituality, and the Search for Meaning

What Einstein Meant by God: Science, Spirituality, and the Search for Meaning

Albert Einstein remains renowned around the world for revolutionizing our understanding of the cosmos, but very few realize that the celebrated scientist had a deep spiritual side. Einstein believed that one wondrous force was woven through all things everywhere—and this sense of the pervasive sacred influenced every aspect of his existence, from his marvelous science to his passionate pacifism. Kieran Fox studied medicine at Stanford University and holds a doctorate in cognitive neuroscience from the University of British Columbia. He is a physician-scientist at the The University of California, San Francisco, where his research centers on the neural mechanisms and therapeutic potential of meditation practices and psychedelic medicines. His new book is I Am a Part of Infinity. More information: https://www.iamapartofinfinity.com/

What Happened to the Intellectual Dark Web?

What Happened to the Intellectual Dark Web?

Outside of the academics and activists whose ideology came to dominate the West in the second decade of the twenty-first century, arguably no group influenced public discourse as much as the Intellectual Dark Web. Challenging the intellectual and cultural orthodoxies that engulfed universities, the media, and big tech, this group—a loose collective of politically diverse intellectuals, commentators, and scholars critical of political correctness, identity politics, and cancel culture—relied on alternative platforms like podcasts, digital magazines, and YouTube to promote free speech, universal rights, and individual liberty. While the term is most commonly identified with Sam Harris, Ben Shapiro, Jordan Peterson, Bret and Eric Weinstein, and Joe Rogan, the group’s concerns and philosophy extended more broadly to include a wide range of individuals who helped mainstream critiques of “woke” culture and a robust defense of free speech, including Steven Pinker, Michael Shermer, Jonathan Haidt, Dave Rubin, Ayaan Hirsi Ali, and Stephen Fry. The Intellectual Dark Web’s coherence began to unravel in the early 2020s due to internal differences (such as over the response to COVID-19 and climate change), and its full legacy and historical impact are yet to be determined. Jamie Roberts is a lecturer in the Department of Government and International Relations at the University of Sydney. His new book is The Intellectual Dark Web: A History (and Possible Future).

Sex and Beauty: The Extraordinary Implications of Darwin’s Strangest Idea (Matt Ridley)

Sex and Beauty: The Extraordinary Implications of Darwin’s Strangest Idea (Matt Ridley)

In all animals, mating is a deal. But few creatures behave as if sex is a simple, even mutually beneficial, transaction. Many more treat it with reverence, suspicion, angst, and violence. Matt Ridley revisits Darwin’s revelatory theory of mate choice through the close study of the peculiar rituals of birds, and considers how this mating process complicates our own view of human evolution. Ridley also explores the scientific research into the evolution of bright colors, exotic ornaments, and elaborate displays in birds around the world. Charles Darwin thought the purpose of such displays was to “charm” females. Though Darwin’s theory was initially dismissed and buried for decades, recent scientific research has proven him newly right—there is a powerful evolutionary force quite distinct from natural selection: mate choice. In Birds, Sex and Beauty, Ridley reopens the history of Darwin’s vexed theory, laying bare a century of disagreement about an idea so powerful, so weird, and so wonderful, we may have yet to fully understand its implications. Matt Ridley is the bestselling author of The Rational Optimist and Viral: The Search for the Origin of COVID-19 (with Alina Chan). His books have sold over a million copies. Ridley served in the House of Lords from 2013 to 2021 and is a fellow of the Royal Society of Literature, the Academy of Medical Sciences, and an honorary member of the American Academy of Arts and Sciences. His latest book is Birds, Sex and Beauty: The Extraordinary Implications of Charles Darwin’s Strangest Idea.
