Journalist/author Robert Bryce interviews Jesse Ausubel about PHE’s work on “peak human” and “peak humans.” The interview covers four dimensions of human performance: the physical (how far and fast can we go?), lifetime (how long can we live and how well?), cognitive (measures of intelligence and learning), and immunity (is our resistance to disease waning?). The podcast was recorded on December 7, 2022. For the audio and transcript, see the Bryce website, and also on YouTube.
