Sleep - A deep dive

Sleep is an important topic which is the focus of many other posts on this site. Joe Rogan is a very popular podcast host. In episode number 1109 [here] he interviews Matthew Walker who is a Professor of Neuroscience and Psychology. They discuss 'all things sleep' including why we sleep, what influences it, the effects of not getting enough of it and how we can improve our sleeping. (Be warned though, Joe is crude at times.)
