Sleep is...well completely mad when you think about it!  Why in the world would we evolve to spend 1/3 of our days, and thus 1/3 of our lives in a state of relative unconscious when there are plenty of animal out there that want to eat us or our families, we could be gathering more food and resources, or anything seemingly more productive than simply laying there in another world.  I dive into this, some recent scientific literature around sleep, and how we can take proactive steps to pull the reins in on sleep so we can use it as another tool in our kit bag that we use to build a more resilient and thus more prosperous and fulfilling life.
