For example, he stole Ummi's face in order to punish Avatar Kuruk for his deep-rooted arrogance, but then he proceeded to tell Aang the names of the Moon and Ocean Spirits as well as their location, so that they could be saved.
Koh stated that Kuruk attempted to slay him some eight or nine centuries prior to the episode, but for that to have happened, he would have had to be older than his immediate successor, Avatar Kyoshi, who was the oldest Avatar in history.
There's no way to defeat Koh but Aang learns that in the past Roku got the best of the spirit. He contacts the former Avatar who reveals he never defeated Koh. Roku simply managed to take something from him, a totem, a pendant with several faces, eyes covered.
Yangchen was the Air Nomad Avatar preceding Kuruk and Kyoshi. Generally revered, she was considered to be a political master. Her reign as Avatar brought about peace, although her interest to placate human desire neglected spiritual concerns and many spirits turned dark and vengeful following her era.

Which Avatar died the youngest?
Originally A Waterbender. Of the Avatars named in the original animated series, Avatar Kuruk died the youngest at only 33 years old. His story is among the most tragic, as well. On his wedding day, his betrothed was sucked into the Spirit World.
Kyoshi was initially upset with Kuruk when he revealed that the spirits feared him because he hunted them, and this nearly caused the ground to collapse around them.
Kuruk confronted Koh in an attempt to save Ummi. When Ummi and Avatar Kuruk were getting married, Koh lured Ummi to the Spirit World, where he stole her face and trapped her forever as punishment for Kuruk's arrogant ways.
Two lifetimes after Kuruk, Avatar Roku was born. In Netflix's The Last Airbender episode 6, Aang seeks out Roku for advice concerning his plight against Koh. Roku reveals that, while he did not manage to defeat Koh in his lifetime, he did steal something from him.
Aang connects with Roku, who is much more pleasant than one would expect, and learns that Roku stole a totem that represents Koh's mother — an item Koh would certainly trade for some human souls.
Avatar Kuruk lived a very short life of 33 years. While looking for his wife, he was killed by spirits that work with Koh. His untimely death is much accredited to his boastful attitude and his laid back personality.
During the final battle, Jake and Neytiri's oldest son Neteyam (Jamie Flatters) is fatally shot by one of Quaritch's men and dies in front of his family.
The two were to be married at the Spirit Oasis in the Northern Water Tribe. However, as she crossed the bridge, she was pulled by an unseen force deep into the water. Kuruk jumped in after her, but could not rescue her in time.
While the leading team including Aang, Katara, Sokka, and Aang's flying bison Appa, is interesting on its own, there are other characters as well who are more amusing than the rest. One of these is Avatar Kyoshi, whom fans call the most violent airbender.
After Aang was brutally struck by Azula's lightning during the coup of Ba Sing Se, Koh attempted to steal Aang's face once again, but ultimately failed when Katara brought him back to life with spirit water. Afterwards, he neither met Aang again in his current life nor his later one as Korra.
A centipede-like creature, he has been in the Spirit World for a long time and has encountered the Avatar throughout different incarnates. He particularly has a grudge against Avatar Kuruk and Roku. Avatar Roku stole a figure pendant of Koh's mother, the Mother of Faces, from Koh himself.
But Raava/Vaatu say they been here since before mankind. And Raava seems to imply the Great Lion Turles were ancient. so the lion turles seem to exist even before Raava/Vaatu time. So with all this in the factor then the Tui and La are the oldest spirits!
The weakest element in Avatar is fire. In terms of combat, other functionalities, and versatility, firebending falls really quite low. Let's look at combat bending. Firebending is one of the best offences as fire and lightning are incredibly difficult to block.
In The Shadow of Kyoshi we learn that Kuruk hunted down and killed dark spirits. This caused him to become spiritually corrupted and die at an early age.
As others here said Kyoshi was 230 when she died, Aang was [technically] 166, first Avatar Wan was also pretty old when he died. The only Avatar we know died young was Kuruk.
There is no known event or conflict that killed Kyoshi. From the information given, she died peacefullye. That would mean she stopped her concentrated meditation and allowed herself to pass on.
When an Avatar dies, the next Avatar will be born into the next nation in the Avatar Cycle. For example, Avatar Yangchen, an Air Nomad, was reincarnated as Avatar Kuruk from the Northern Water Tribe, followed by Avatar Kyoshi from the Earth Kingdom, and Avatar Roku from the Fire Nation.
