“An interesting illustration of the uselessness of a brain in a body without movement is the sea squirt, which spends the first part of its life as an animal moving around, and the second part attaching itself to a rock and then camping out as a plant.  As soon as it settles down, does it use this time as an opportunity to meditate or think about the meaning of life?  No, it eats its brain for the energy.  This should make us very curious about what happens to a human brain in a body that spends too much time on the couch.”
