The body is sort of a pain. It has to go to the bathroom. It has to be comfortable. But the spirit is indestructible. It can move at the speed of light.
My final question: Why are we not looking at moving out onto the sea? Why do we have programs to build a habitation on Mars and we have programs to look at colonizing the Moon but we do not have a program looking at how we colonize our own planet, and the technology is at hand!
