Ken and Dawn return in today’s podcast to answer more listener questions.

Back at the beginning year, Ken and Dawn hosted their first Ask Me Anything episode. In that episode, they promised not to wait another three years and 83 episodes before once again addressing listeners’ questions.

A steady stream of new questions have poured in since that first Ask Me Anything episode. Today, Ken and Dawn take turns answering questions about exogenous ketones, daily allowances of protein, healthy fats, black holes, long-duration space flights, decompression sickness, the future of AI, sloppy science, and much, much more.
