A thought

Sometimes I think about the drive that humans have in life, and compare that to the drive that dogs have in life, and compare that to the drive bees have in life, and to the drive that diseases have. And I think, there is no one point at which the drive to continue living changes between organisms. What does a bacterium have to live for? The same thing we do. And it seems, bacteria live simply because they do. There isn’t purpose to them, they simply exist. And thus it seems, we live simply because we do. There isn’t purpose.
