I enjoy listening to National Public Radio (NPR) when I have long drives. I've set up my iPhone to download podcasts of several programs including "Radiolab" and "This American Life" as they tackle interesting topics in depth.
I came across a recent podcast called "Death and Taxes" and HAD to post a link to it from my blog. I have an older post from my own blog on dying that triggered a lot of really deep conversations in my own clinic and from several readers who reached out to me afterward.
The NPR podcast starts out with a 3-4 minute introduction on "inevitability" which doesn't really fit well with the rest of the podcast, but the next 40 minutes are sensational. While the topic isn't the easiest to encounter, I would encourage any readers of my blog to listen to the 40 minute podcast. It is really good. Click on the orange button "Launch Player"
