can anyone tell me how a person born in 1984 be in her 80s in 2010-20.
i am thinking now that Chinese MCU fanfiction author don't research anything before writing they don't even know the age of main characters.
I haven't read the novel, but if you're talking about Natasha, then both are correct.
In the comic she was born around the 1930's or at the end of the first world War so you do the math.
In MCU she's born in 1984 .
