Some Jedi achieved immortality as Force spirits, their consciousness preserved in the Force. Every living being became one with the Force during the process of dying.
Who was the oldest Jedi to ever live? Yoda was a wise, experienced, and powerful Grand Master of the Jedi of an unknown species and the oldest known prophet in existence (having lived at least 900 years), considered the wisest and most powerful Jedi Master within the Star Wars universe.
He studied the living Force and learned from the Force Priestesses how to retain consciousness after death; he also learned physical manifestation was possible but didn't achieve it because his training was incomplete. By using the living and cosmic Force in tandem, he was able to unlock the secrets of eternal life.
Could a Sith live forever? Yes a Sith Lord can, and already has. Darth Andeddu created the Dark Rituals to transfer his essence from body to body to ensure eternal life. He was ultimately killed by his followers but he lived hundreds of years before that murder.
It is presumed that Qui-Gon, taught yoda as well as Obi-Wan to become a “force ghost”. And when you're a force ghost, you live on. There is no other death. You are immortal through the force.

According to Darth Sidious, Darth Plagueis was a powerful Sith Lord who was able to use the Force to influence the midi-chlorians to create life, a power that was reportedly to be extremely rare for one sensitive to the Force to possess, and could even be used by certain Sith Lords to prolong or even cheat death.
Qui-Gon Jinn was more attuned to the Force than any other prequel Jedi, and that's one reason why Emperor Palpatine needed him dead.
Darth Sidious was able to cheat his upcoming death by transferring his spirit into a clone body while falling into the reactor core of the second Death Star. He later sought to prolong his existence by futilely manipulating his grandchild Rey into killing him so he could live further by possessing her body.
Born on Coruscant circa 80 BBY (Before the Battle of Yavin), Qui-Gon trained as a Padawan under Jedi Master Count Dooku.

The species had a very long life expectancy, spanning at least several centuries; Yoda lived nearly a thousand years before dying of old age, and they aged very slowly, remaining in infancy for at least fifty standard years.
Wookiees had an average lifespan of 400 standard years, and they appeared not to age over a span of fifty years.
Darth Sidious, publicly known as Sheev Palpatine from Naboo, became the Dark Lord of The Sith after betraying and murdering his Sith Master Darth Plagueis. Sidious was the Dark Lord of the Sith during the last years of the Republic and the rise of the Galactic Empire.

As the first Dark Lord of the Sith, Ajunta Pall founded the first Sith Empire and expanded it onto other worlds. The Sith took over the planet Ziost and created it as their capital and as Pall's new home. Pall eventually died after serving the Empire for many decades, but his Empire lived on.
At the end of the third episode, you know, the Jedi Order is all but destroyed. Those who aren't killed have gone into hiding and can't communicate with each other. For ten years, Obi-Wan has been in hiding, can't communicate with any of his old comrades. He's living a pretty solitary life, he can't use the force.
In the book, Palpatine is revealed to have discovered the "secret to immortality" from his former master, Darth Plagueis, using this knowledge to survive after his death in Return of the Jedi.
The two Jedis had a close relationship in both the original and prequel trilogies, so the iconic character's absence was curious to some.
