I think to be human is to wonder what happens after we die. Isn’t that the essential question that people have been asking since we learned that life does not go on indefinitely? I am a typical over-thinker so it is a question I come back to again and again. Radiolab’s “After Life” episode is chillingly good as it looks at the after life. It is through that episode that I learned about neuroscientist David Eagleman’s book Sum: Forty Tales from the Afterlives. It is a very short book, an easy read, that is actually a lot less morbid than it sounds. Some of the afterlives it presents are funny, some silly, and others are as beautiful as you want to believe.
