question:  Why did most of the men and women have a young appearance?
context: Bodyguard By CHRISTOPHER GRIMM Illustrated by CAVAT [Transcriber's Note: This etext was produced from Galaxy Science Fiction February 1956. When overwhelming danger is constantly present,of course a man is entitled to have a bodyguard. Everyone in the room was aware of the big young man, and most of the humans present were resentful, for he handled himself consciously and arrogantly, as if his appearance alone were enough to make him superior to anyone. Even the girl with him was growing restless, for she was accustomed to adulation herself, and next to Gabriel Lockard she was almost ordinary-looking. As for the extraterrestrials—it was a free bar—they were merely amused, since to them all men were pathetically and irredeemably hideous. There was a short man standing next to the pair—young, as most men and women were in that time, thanks to the science which could stave off decay, though not death—but with no other apparent physical virtue, for plastic surgery had not fulfilled its bright promise of the twentieth century. And that, coming on top of Gabriel Lockard's spectacular appearance, was too much. His eyes studied the other man's incredibly handsome young face, noted the suggestion of bags under the eyes, the beginning of slackness at the lips, and were not pleased with what they saw.

As a matter of fact, no real identification was possible, for he was no one and had been no one for years. Each time it happens, there's a ... well, there's no experience to match it at a thrill-mill." To the girl's indignation, the stranger not only hauled Gabe out onto the dripping grass first, but stopped and deliberately examined the young man by the light of his minilume, almost as if she weren't there at all. Only when she started to struggle out by herself did he seem to remember her existence.
