In the photograph you looked older than the cliché—older than the hills.

Really small organisms (viruses and rickettsia, for instance) aren’t motile (for reasons we will soon be able to guess), but we can explore the consequences of their hypothetical mobility by resorting to science fiction. In a classic example of Hollywood science, the cast of the film The Fantastic Voyage (1966) is placed in a submarine, reduced tremendously in size, injected into the blood stream of a human being, and asked to cruise to the brain to correct some malady.

The reply to this objection is that the inability to suffer is the worst punishment that can befall a man ; he is by that same thing deranked from humanity ; the lowest hell into which a man can fall is that hell where there is no feeling, the hell in which a man may be without knowing it.

That little dog meant everything to me.
