From Wikipedia Entry:

"Tin Soldier" tells the story of Maris, an ex-soldier who, following wounds sustained in battle, has received cybernetic implants that, as a side effect, slow his aging to "about five years for every hundred" (he is 115 years old as the story begins, though physically he looks "about twenty-five"), and Brandy (short for Branduin), a female starship crew member.[1]
