"...she spent most of her life in ordinary time, sixty seconds to the minute. As a field agent, I'd go through days, weeks, or months between saying good-bye to her in the morning and returning for dinner - an interlude during which she could pursue her career without me underfoot." (Time Patrol, p. 345)
Sometimes months between breakfast and dinner? That implies some psychological dislocation. Farness continues:
"My cumulative age was approaching a hundred years.
"Sometimes it felt like a thousand. That showed." (ibid.)
Again I wonder: how old is the oldest Time Patrol agent? And do some of them become the Danellians?
Time seems to accelerate as we age. How would this work in an indefinitely extended lifespan? Especially for a time traveler? I read somewhere the speculation that the apparent acceleration would slow down some time in the second century but where did I read this? Was it in a work by Poul Anderson?
