The World as You’ll Know It: The Future Of Aging

Dr. Eric Topol, a leading cardiologist and author of 'Super Agers,' delves into the science of healthy aging. He uncovers the surprising impact of sleep, exercise, and diet, particularly the Mediterranean diet, on longevity. The conversation also touches on the crucial role of social engagement and mental health in aging well. Topol demystifies common longevity myths, advocating for informed health choices while shedding light on environmental factors like pollution. He emphasizes the urgent need for societal adaptation to the increasing human lifespan.

Women tend to live longer than men, even under the most difficult conditions like famines and epidemics. While it’s true that women tend to go to the doctor more and engage in less risk-prone activities, behavior alone doesn’t explain this phenomenon. In this episode, demographer Virginia Zarulli tells us about the implications of the startling fact that, in times of extreme hardship, it is often infant girls outliving infant boys that contributes most to the gap in longevity. Neurologist Dena Dubal, who has spent years studying the influence of the second X chromosome that females carry, explains how research into how women age will benefit men, too. And neuroscientist Lisa Mosconi talks about the impact of sex hormones on aging and why women are disproportionately susceptible to certain age-related diseases.

We’ve known about Alzheimer’s and its devastating effects for more than 100 years, and have been predicting an imminent cure for at least the last 25. So why is it that after so many years of research and unrelenting loss, we’re not further along in our progress towards a cure? In this episode we consult three experts who have dedicated much of their lives to understanding this question. Neurobiologist Karl Herrup is the author of “How Not To Study a Disease: The Story of Alzheimer’s.” Charles Piller is a journalist who spent years researching the scandals that recently rocked the Alzheimer’s community. Donna Wilcock is a neurologist who has been studying Alzheimer’s disease and other forms of dementia for decades, and is also the editor-in-chief of the official journal of the Alzheimer’s Association. Together they help explain where we went wrong, and suggest where we might look next in our search for a cure.
