Bucky Barnes, like Steve Rogers, has lived for several decades due to cryogenic freezing and the super-soldier serum. Bucky's life expectancy could potentially surpass Steve's 116 years, depending on circumstances. Despite outwardly aging at the same rate as Steve, Bucky can still live for at least another 80 years.
Because the strong man who has known power all his life may lose respect for that power, but a weak man knows the value of strength, and knows compassion.” This is also why Steve chooses Sam to be the next Captain America.
Taking the experimentation, cryogenic freezing and time skips into consideration, Bucky is physically somewhere in his mid-30s by the time The Falcon and the Winter Soldier takes place, making him appear seventy-some years younger than his chronological age.
Bucky was born on March 10, 1917, so he was already older than Steve, who was born on July 4, 1918, even before they became enhanced. Further, Captain America was frozen and preserved as he was in 1945 without thawing for nearly seven decades before he was revived.
He fell of the train and hydra took him but how did they keep him the same age? He was called The Winter Soldier as Hydra kept him cryogenically frozen until they had a mission for him. So he physically aged much slower than his chronological age.
Why Bucky Barnes Ages Differently From Steve Rogers
Why did Captain America age but not Bucky?
No, that's because Bucky was kept on ice in between his assassination missions. Steve Rogers didn't actually age until he went back in time and instead of being frozen for 40 years he lived out his life with Peggy Carter.
Bucky owes his youthful appearance to repeated cryo-freezes orchestrated by the Russians. He possesses no super powers and never received a form of the Super Soldier Serum as many assume, but continues to operate at peak human ability.
The movie version contradicts this with new birthdays for both with Steve Rogers being born on July 4, 1918 while Bucky was born a year earlier on March 10, 1917. In the comics, Steve is 3 years older than Bucky while in the MCU, Bucky is actually older than Steve by a year.
We see that he's deprogrammed 6 months before the snap in FATWS. He's then snapped away and comes back 5 years later. FATWS takes place 6 months after he comes back. So Bucky is likely 33 physically while chronologically being 107 (FATWS takes place in April 2024, so Bucky's wrong about being 106).
The Super-Soldier Serum dramatically prevents individuals from aging due to the regeneration of healthy cells. For instance, Dr. Kudrin has stated that Natasha "don't age as fast."
Bucky Barnes, like Steve Rogers, has lived for several decades due to cryogenic freezing and the super-soldier serum. Bucky's life expectancy could potentially surpass Steve's 116 years, depending on circumstances. Despite outwardly aging at the same rate as Steve, Bucky can still live for at least another 80 years.
According to Google, comics Bucky was born March 10, 1917. If we presume that's the case for movie Bucky, he'd have been 24 when the US declared war against Japan and 28 when the war was in it's closing days, which is generally the time frame for when he disappeared.
Barnes is notably targeted by T'Challa, the Black Panther, who mistakenly believes Barnes kills his father. Iron Man also strongly retaliates against Barnes after finding out that the Winter Soldier was responsible for the death of Stark's parents while under HYDRA control, and that Rogers hid the information from him.
Bucky had resentment towards Sam for giving up the shield. The therapy session showed the issues they had towards each other. Bucky wanted to know why Sam gave up the shield that Steve trusted him with and was Steve's whole legacy. Bucky emotionally says that if Steve was wrong about Sam then he was wrong about him.
As a villain, it made sense to present the Winter Soldier as unstoppable, to make him a better foil for the heroes he fought. With his reformation comes an increased vulnerability; physically weakening him helps the audience better identify with him and ensures he can't simply knock out opponents with one punch.
James Buchanan “Bucky” Barnes enlists to fight in World War II, but eventually literally falls in battle. Unfortunately, the evil Arnim Zola recovers him and erases his memory, turning him into a highly-trained assassin called the Winter Soldier.
Surviving the war and believing Rogers had died during his last mission, Bucky eventually married Rogers' fiancé, Peggy and had two children, Marvin and Rebecca.
Early Life. James Buchanan "Bucky" Barnes was born in 1925. In 1935, he tragically lost both of his parents early in his life; his mother, Winnifred Barnes had died when he was a child and his father, George Barnes had died in an accident while in basic training at Camp Lehigh.
In the Marvel Comics, Steve Rogers appears able to live forever without aging. While he can be killed, he has lived for huge periods of time without aging at all because of the effects of the super serum and how it interacts with his cells.
Following Bucky Barnes' fall from Arnim Zola's speeding train, he suffered injuries that included the loss of his left arm. The prosthetic arm was only a portion of the reconstruction efforts HYDRA used in turning Barnes into their deadly assassin.
The Hydra experimentation on Barnes causes him to survive his fall, and he is recaptured by the Hydra wing of the Soviet Union, where he is tortured and brainwashed by Arnim Zola and turned into the Winter Soldier, a mind-controlled super soldier with a metal prosthetic arm.
After successfully brainwashing super soldier Bucky Barnes to be their assassin, HYDRA had him cryogenically frozen in a cryostasis chamber to preserve his longevity and prevent him from aging.
In terms of raw strength, Captain America is typically portrayed as being stronger than the Winter Soldier, although the Winter Soldier's combat skills and agility can still make him a formidable opponent.
