Steven Kotler, New York Times bestselling author, award-winning journalist, and the Executive Director of the Flow Research Collective, returns in Part 2 of this interview, tackling weighty topics like the denial of death, embracing change as foundational to aging, the illusion of self, the "long slow rot" theory, how aging is a "use it or lose it" game, how Freud kicked off 90 years of scientific tail-chasing, wisdom vs. expertise, and why guest host Stephanie Maas may just live forever.
