Gimli lived to be at least 262 years old, as he sailed West to the Undying Lands (Aman) in the year FO 120 (Fourth Age 120) after Aragorn's death, having been born in TA 2879 (Third Age 2879). He was the first Dwarf to ever journey to the Undying Lands, departing from Ithilien with Legolas, though his exact age at departure was over 262, and his ultimate fate isn't specified, according to lore.
They build "great works" in Rohan and Gondor, and replace the ruined gate of Minas Tirith with one made of mithril and steel. After Aragorn's death, Gimli (then 262 years old) sails with Legolas into the West, becoming the first Dwarf in the Undying Lands.
After Faramir's death at the age of 120, his son succeeds him.
No. It is because of the fewness of women among them that the kind of the Dwarves increases slowly, and is in peril when they have no secure dwellings. For Dwarves take only one wife or husband each in their lives, and are jealous, as in all matters of their rights.
Gimli was 139 years old (born in 2879 of the Third Age) when the Fellowship of the Ring set out from Rivendell, making him 52 years older than Aragorn.
Legolas is an elf, so he is immortal. However, he is only immortal in the sense that he will never die of old age or sickness. He can die in battle.
It's not the years; it's the mileage. Gandalf isn't a Maia in the same way Sauron is. He was sent to middle earth as an old man, so his body is much more real than Sauron's “raiment”. He can't use his power to the same extent, he can't change his forms at will.
Legolas does not marry or have any children, based on the appendix of The Lord of the Rings. Regardless of who his mother was, Legolas is the last of his line. When he sails into the West at the beginning of the Fourth Age, he leaves no family members behind.
Sometime afterward in the coming years before his expedition in TA 2989, Balin would visit Bilbo at least one more time. During this visit to the Shire, Balin met Bilbo's newly adopted heir of Bag End, Frodo, and the young Hobbit would come to learn of some of Balin and his Uncle's travels to the lonely mountain.
There is some debate over whether he had been there before, or how long he had been incarnated as Gandalf before he arrived in the Third Age. But he spent at least 2021 years as Gandalf. Long as that is by mortal reckoning, it was less than 4% of his ~55,000 year total lifespan so far.
We have a date of death for Faramir in 82 of the fourth age. We don't have a date for Eowyn but Eomer died in 63, she probably was similar date. Faramir was 12 years older than her so if she died in around 63 it would be a 35 year difference in life span.
Tolkien's description of Gollum conforms to a Catholic – and Thomistic – account of envy, which is a “sadness of the soul”; and it is Gollum's unbearable sadness and his unquenchable desire for the one Ring that marks his character.
After supper, Fíli and Kíli played small fiddles that they had brought in bags. The brothers were the youngest of the company by some 50 years, with Kíli being five years younger than his brother. Although not twins, the two brothers were inseparable throughout the adventure.
As far as how old Frodo is when he dies, the answer is...well, we don't know. Because two years after the end of his quest, Frodo leaves for the earthly paradise of Valinor and doesn't return to Middle-earth, so what happens to him is unknown. He could be dead, he could be alive—he's the Schrödinger's cat of Hobbits!
He dies at the age of 210, after 122 years as king. The graves of Merry and Pippin (who had died in Gondor 58 years earlier) are set beside his. He is succeeded on the throne by his son, Eldarion. Arwen, heartbroken by the loss of her husband, dies shortly afterwards in Lothlórien.
The movie the Battle of Five Armies expanded on Tolkien's canon by saying that the white gems Thranduil wanted back from the dwarves were originally intended for her, but that she was captured and taken and tortured to death by Gundabad orcs before the order was completed.
At the end of October, worn down by weeks of tension and wretched conditions, Tolkien contracted trench fever and was sent back to hospital in Birmingham. He remained unfit for the rest of the war.
Therefore it is feasible that he would have never actually had a wound before, especially as it took all that from Bolg to get the smallest nosebleed. Therefore seeing his own blood came as quite a shock. And demonstrated the violent nature of his foe to both Legolas and the audience.
In the late First Age, Finrod and Galadriel came to Doriath as guests of Thingol. There, Celeborn and Galadriel met, fell in love, and were soon betrothed. Galadriel remained in Doriath with Celeborn after Finrod went to the Caverns of Narog to establish the stronghold of Nargothrond.
In 1904, Mabel was diagnosed with Type 1 diabetes. Her friend Father Francis Xavier Morgan, who lived nearby in the Oratory which conducted St Philip's School, arranged for the family to rent rooms in the Oratory's lodge cottage, where Mabel died in November 1904.
