For years, cardiologist Eric Topol hunted for the rarest people in America: those over 80 who had never been sick. When he finally found 1,400 of them, he made a shocking discovery. It wasn't their genes. These "super agers" were often the last ones standing in families where everyone else died decades earlier. So what separates people who live into their 80s or 90s feeling great from those who battle chronic disease? In his new book, Super Agers, Eric reveals what the science actually shows, shares practical advice you can use at any age, and takes on the bro scientists selling false promises along the way.

This is part one of our interview with Eric. Part two will be available right here next week. If you can't until then, you can listen now on the Next Big Idea app: https://nextbigideaclub.com/app/
