History Main / LongevityTreatment

A subtrope of ImmortalityInducer, usually results in LongLived or TheAgeless. BrainUploading counts when the brain is downloaded into a clone or other biological body, but not if into a machine. Compare with FountainOfYouth, which ''regresses'' one's biological age to a younger stage rather than extend one's maximum lifespan.

* The ''Literature/RedMarsTrilogy'' features a specialized gene therapy referred to as a "gerontological treatment". The books span over two hundred years and most the major characters, many of whom were ''already'' in their 40s and 50s at the start of the series, are alive and active that entire time due to repeated use of the treatment.

* In MikhailAkhmanov and Christopher Nicholas Gilmore's ''Literature/CaptainFrenchOrTheQuestForParadise'', the Cellular Regeneration treatment available on most worlds has, effectively, turned humanity into TheAgeless. People choose when to "freeze" their age with most picking sometime in their 20s, although some wait until 30 in order to look "more mature". The only people who die of old age are either criminals on worlds where capital crime is punished by aging (reversing the treatment) and on recently-settled worlds where CR machines have not yet been set up. It's mentioned by the titular protagonist that, even before CR, various treatments (including cloned organs and blood vessel cleansing) have extended expected lifespans to centuries.

* In ''OrionsArm'' most [[HumanSubspecies nearbaselines]] are genetically engineered to live about 500 years. But due to medical nanotechnology and brain uploading most in the Sephirotic Empires live to 3,000 before succumbing to ennui or [[AscendToAHigherPlaneOfExistence transcending]].

* A plot point in ''Webcomic/SchlockMercenary'' is "Project Laz'r'us", which was intended to circumvent humanity's [[WeAreAsMayflies short lifespans]] in comparison to many other sophonts using hyper-advanced nanotechnology. The nannies are also capable of repairing a clinically dead host and even making internal backups of the brain. The species from whose computer equipment carbosilicate amorphs has evolved already made themselves immortal and ran into several layers of problems. Still, there's a few remaining individuals alive and sane after their twelve million of Terran years, "[[http://www.schlockmercenary.com/2007-07-14 give or take a little bit]]".

* The spice melange in ''Literature/{{Dune}}'' can extend lifespans up to 300 years.
** The prequels reveal that the Old Empire had a treatment that could extend lifespans even longer, and without causing a drug dependency. When one of the characters receives it (allowing him to stick around for the next few books), it's mentioned to be extremely painful.

* In JohnScalzi's ''Literature/OldMansWar'', rejuvenation treatment via consciousness transfer to a genetically enhanced body is only available to military personnel--and the minimum age for joining the military is 75.

** ''VideoGame/TheSims3'' has a plant called '''life fruit''', which expand at least one day of a sim's life. Said fruit is a critical ingredient in the Ambrosia recipie that resets a Sim to the start of their current life stage.

* Poulsen treatments in Creator/RobertReed's novel, ''The Remarkables''. It can greatly expand one's life (beyond the already genetically enhanced ~150 year lifespan), though the treatment leaves visible marks - one of the characters who has had extensive treatments has an almost young face, but wrinkled hands and oddly colored skin.

* The prolong treatments in the ''Literature/HonorHarrington'' books. It's most blatant example is Honor's mother, Allison, who at 90 is still very attractive and capable of bearing children. And since Honor is a second generation recipient, she's likely to live even longer. Also, people not only look very young for decades, they also have the hormonal levels corresponding with the apparent age ''for decades''. In the latter books, prolong becomes a key indicator of how socially and economically evolved a planet is: if you look old, it likely means you're poor. When the [[spoiler:Star Empire of Manticore]] is created, receiving prolong is made a fundamental, inalienable right of every citizen.

* In ''Webcomic/QuantumVibe'', rejuvenation treatments are just as readily available. One of the main characters is reportedly in his third century, but there's evidence that he's ''[[ReallySevenHundredYearsOld over 500 years old.]]''

* Citizens of ''TheCulture'' are genetically engineered to live for centuries, longer if they feel like it.

* In the ''VideoGame/MassEffect'' series, humans commonly live to 150 or so due to gene therapies and drugs. This puts us in the mid-range for lifespans in that universe.

* Longevity treatments exist in the ''MutantChronicles'' setting, but are hideously expensive, require invasive surgery and have to be combined with an extremely strict regimen of diet and exercise to be effective. Very few people find it worthwhile.
