 How does Giles change with the knowledge of his aging?
For eighty years now, they’d been sending out the little ships that vanished at greater than the speed of light, equipped with every conceivable device to make them return automatically after taking pictures of wherever they arrived. The discovery that men could live practically forever had put an end to most family ties; sentiment wore thin in half a century—which wasn’t much time now, though it had once seemed long enough. Pre-setting a course may take centuries, if we can ever master it. GILES FOUND himself lying on his couch, partially undressed, with the pillows just right and a long drink in his hand. Some were older than Giles could remember—knee reflex, blood pressure, pulse and fluoroscope.
 He feels a new fondness for his son and family.
 He resigns to his fate, because he doesn’t know what else to do.  He doesn’t. He goes right back to doing what he’d been doing out of habit.  He feels a new fondness for his son and family.  He shows a much greater appreciation for every aspect of his life.
