Jesse Ausubel is the director of the Program for the Human Environment at Rockefeller University and the recent winner of the prestigious Nierenberg Prize. In his second appearance on the podcast (the first was on October 12, 2021), Ausubel talks about his new work on “peak human” and “peak humans,” why we appear to be reaching the limits of human potential, immunity to disease, “nature deficit disorder,” and why -- after a lifetime of being a fan of the New York Yankees -- he has quit watching sports.
