Looking for a science fiction story I read years ago, about teleportation gateways that the user finds are making him younger when he travels through them.

    This question is very terse and would be greatly improved by going through the checklists here; How to ask a good story-ID question?

  • The more information you can provide about the story (and when/where you read it), the more likely it is that someone can identify it for you. We recommend that you look at our Guide: How to Ask a Good Story-ID Question and see what info you can add to this question. Aug 20, 2018 at 16:35

    Having said that, I immediately thought of Niven, A World Out of Time. Aug 20, 2018 at 16:36

    Larry Niven's "A World Out of Time" occured to me too. It uses this idea. The protagonist was a man from our near future who becomes a starship pilot. Time dilation places him in a far future solar system with a very changed Earth, now orbiting Jupiter. Do the words "Dicta" or "Boys" mean anything to you? Aug 20, 2018 at 20:44

    "Fax machines" that heal injuries and restore yiuth, making people effectively immortal, are a prominent feature of Wil McCarthy's Queendom of Sol novels, starting with The Collapsium. There's also a lot of dangerous mucking-about with gravity.

This is not much to go by, but in Exile's Gate, the fourth of the novels about the heroine Morgaine by C. J. Cherryh, the viewpoint character (Margaine's ronin servant, Nhi Vanye) is reverted to a fixed age every time he passes through a teleportation gate. Morgaine had programmed the gates to do this, to heal his injuries.

Since the plot of the whole series involves Morgaine traveling from planet to planet through the gates and closing them behind her, this is a potentially important plot point. It means that Vanye will not be able to outgrow his approximately twenty-year-old appearance as long as he continues to travel through the gates. However, since the novels ended after Exile's Gate, the issue was not pursued too extensively.

This might possibly be the Damon Knight story "Ticket to Anywhere" (1952.) It has a network of teleportation booths that don't make you younger, but do temporarily stop the aging process while you're using them. You can read a copy at the Internet Archive, and it's been anthologized a number of times.
