Human Jedi generally live longer than average humans, extending their lifespan from the typical 100-120 years to potentially 150-200 years, thanks to their connection to the Force, though some rare cases in Legends lore even reach centuries, with the Force potentially extending life far beyond typical biological limits, though most don't achieve true immortality.
In the EU, yeah, the Force can extend one's lifespan. Master Fay is an obvious example of such(who lived for centuries), but it's noted in the New Essential Guide to Alien species, that Human Jedi can live up to 200 years.
Typically, Humans had an average lifespan of 100 to 120 standard years. Those who were keenly atuned to the Force, a ubiquitous and binding power that suffused the whole Known Universe, could live up to 200.
With the death of T'ra Saa at Taivas, K'Kruhk became the oldest and most experienced of the surviving Jedi and participated in the alliance's final assault on the Sith-held Coruscant. Following the deaths of Darth Krayt and Roan Fel, K'Kruhk became one of the three Triumvirs of the restored Galactic Alliance.
Force-sensitive humans have been recorded to live up to 200 years. Was there any explanation given in legends for why force sensitive people had a significantly higher life expectancy? No, but it's basically amounts to a "healthy lifestyle".
Force spirits
If you strike me down, I shall become more powerful than you can possibly imagine." Some Jedi achieved immortality as Force spirits, their consciousness preserved in the Force.
In Star Wars lore, Order 37 was a grim Clone Trooper contingency plan to capture a wanted individual (often a Jedi) by taking a civilian population hostage, locking down the area, and threatening mass execution if the target wasn't surrendered, making it a horrific tactic used by the Empire to force Jedi compliance. It was considered more brutal than Order 66 because it targeted civilians directly, forcing Jedi to often turn themselves in to save innocent lives, as seen on planets like Bellassa.
Because these Canon "Gray Jedi" utilize the dark side, it's impossible for them to be in balance. The dark side corrupts, destroys, and tears down in Canon; it's not a force for good or altruism. Think starwars.wikia.com/wiki/Kylo_Ren.
In the original trilogy, Yoda lives in solitude on the swamp planet Dagobah. He is introduced as a former mentor of the Jedi Master Obi-Wan Kenobi, and he trains Luke Skywalker in the ways of the Force until his death at the age of 900.
The clone commando RC-1136, known as Darman Skirata, got Jedi Knight Etain Tur-Mukan pregnant during the Clone Wars, resulting in their son, Venku Skirata, a Force-sensitive child born outside the Jedi Code's restrictions. Their forbidden relationship and child's birth were detailed in the Republic Commando novels, highlighting the complexities of clone troopers' development and the strictures of the Jedi Order, as Etain was killed shortly after Order 66 while protecting her family.
This makes sense, given that one of the only other known members of his mysterious species — Yoda — lived to the ripe old age of 900. Such slow-aging, long-living creatures are not unique to the galaxy far, far away where Star Wars is set.
According to Wookiepedia.... Palpatine was about 88 years old when he died. He was human so I would think that he still would've died in 20 years at the most but you don't know what kind of advantages his power would've given him.
It had something to do with how they use the force to keep in peek physical health and slow down the natural degrading of the body. Of course, I'm sure that in the star wars universe there are countless ways to increase ones lifespan, such as cybernetics and space medicine.
No, lightsabers can't block bullets. Here's a great video that explains why. The idea was actually put into issue #18 of the Dark Lord of the Sith comic series. During the hunt on Chandar's Folly, Tarkin's team armed up with slugthrowers (firearms) and flamethrowers, two things Vader couldn't block with his lightsaber.
Vernestra "Vern" Rwoh.
Yoda. 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.
Zorba the Hutt's Revenge (1992), a young-adult novel by Paul and Hollace Davids, identifies Jabba's father as another powerful crime lord named Zorba and reveals that Jabba was born 596 years before the events of A New Hope, making him around 600 years old at the time of his death in Return of the Jedi.
Flat out duel: Yoda smashes if there isn't anything for Palpatine to use, and it's just a lightsaber fight with some force abilities. Closed in area: Yoda, he can easily outmaneuver Yoda. Large area: Palpatine, he can get put distance between them and force lightning Yoda or throw heavy stuff on him.
Tl:dr - We know Jedi can leap great distances (as demonstrated by Luke in ESB, Qui-Gon and Obi-Wan in TPM, and Sidious and Yoda in ROTS), but can't actually 'fly', presumably because the effort in maintaining persistent flight over a long distance would be too great.
Chirrut Îmwe. Deeply spiritual, Chirrut Îmwe believes all living things are connected through the Force. His sightless eyes do not prevent him from being a highly skilled warrior.
Ahsoka Tano from Star Wars: The Clone Wars can also technically be called a Gray Jedi, due to her forsaking the ways of the Jedi, but still following a path of good. However, neither of these two ever trained to use the dark side of the Force, so they are arguably not "true" Gray Jedi.
Form VII (Juyo), the "Ferocity Form," was banned by the Jedi Order because it required channeling aggression, anger, and other intense emotions to fuel its wild, relentless, and unpredictable attacks, which closely skirts the dark side and risks corrupting the user, a direct violation of the Jedi Code's emphasis on peace and emotional control, even though Mace Windu later adapted it into the controlled Vaapad variant for a select few.
BACKGROUND INFO: What is Order 69? Order 69(AKA "clean up") was the idea to kill the entire clone army in one sitting, leaving the Jedi defenseless and exposed by the sudden departure.
Clone 99, or simply 99, was a human male clone of Jango Fett bred to be a clone trooper for the Galactic Republic's Grand Army. However, he was rendered genetically defective in the cloning process, and instead of serving in the army, he was assigned to be a maintenance duty clone on his home planet of Kamino.
