Thanks for the chuckle. One is then left wondering whether our far
future, Clarkeian "Against the Fall of Night/City and the Stars",
descendants will enjoy *two* siestas per day. With inhabitants being
reconstituted every few millennia from a computer database, one might
argue that evolution will have indeed ceased - so they won't be
adapting to the lengthening day by natural selection. Of course,
they may have artificially stabilized the Earth's rotation by that
point, too :-) Does anyone remember if Earth-Moon dynamics plays a
role in the story?
