But according to Luke
Luke 2:36–38 There was also a prophet, Anna, the daughter of Phanuel, of the tribe of Asher. She was very old; she had lived with her husband seven years after her marriage, and then was a widow until she was eighty-four. She never left the temple but worshiped night and day, fasting and praying. Coming up to them at that very moment, she gave thanks to God and spoke about the child to all who were looking forward to the redemption of Jerusalem.
One way to read this is that she was 84 when Mary and Joseph presented Jesus to Simeon in the temple. Or another way is to add it all together. So assuming she was married as a teenager, let's say 15, she was married until 22, and then lived as a widow for 84 years which puts her at 106. Extremely rare, but not impossible. No matter what, people did live into their 80s even back then.
