Iceland, Eyjafjallajökull – May 1st and 2nd, 2010 from Sean Stiegemeier on Vimeo.

At first it seems cool, but I don’t think the power generated is worth it.

What happens at the moment when we slip from life…to the other side? Is it a moment? If it is a moment, when is that moment? And what happens afterward? It’s a show of questions that don’t have easy answers. So, in a slight departure from our regular format, Radiolab brings you eleven meditations on how, when, and even if we die.

My favorite idea presented is that we die three deaths. One when our physical body dies, one when we are buried, and finally when our name is spoken for the last time.
