"He will be subject to the deterioration of old age, the same as we are, won't he?" Macker asked.
"Of course," Toolls said, "but that's the only thing that will be able to bring him down. He cannot be harmed by any force this 'light' world can produce; he is impervious to sickness; and he will live indefinitely."
"Indefinitely?"
"As his world reckons time. Their normal life span is less than a hundred years. Ours is over five thousand. He will probably live approximately twice that long, because he will be subjected to less stress and strain, living as he does on a world of lighter elements."
"Then we have truly made a superman," Macker's tones inflected satisfaction. "I wish we were returning this way in a thousand years or so. I'd like to see the monumental changes he will effect."
"We may at that," Remm said, "or others of our people will. He will probably be a living legend by then. I'd like to hear what his race has to say about him. Do they have names with which to differentiate individuals?"
"Yes," Toolls said. "This one has a family designation of Pollnow, and a member designation of Orville."
"It will be necessary for us to leave in exactly ten minutes," Remm reminded them. "Our next stopping place—the red star—will reach its nearest conjunction with this planet by the time we meet it out in space."
"Then we will have time to do nothing more for him before we go," Macker said. "But as far as I can see we've forgotten nothing, have we, Toolls?"
"Nothing," Toolls answered. "No—we forgot nothing."
