Our guest on this episode is Dan Levendowski. Dan is the President and Co-founder of Advanced Brain Monitoring which is a neurodiagnostic device company that has been working on the science of human sleep for about 20 years.

Dan is returning to Bulletproof Radio for the second time. His first appearance was alongside Phillip Westbrook back in 2014. Back then, Dan's company had a new sleep apnea device called Night Shift, but in this episode, we dive into the topic of why so many people do not get good quality sleep, why that is such a problem, and also what we can do about it.
