[DC] How good is Vandal Savage's memory?

How much does he remember about his life and how much has he forgotten over the last thousands of years?
gpt
He has forgotten a lot of things, including (he once lamented) a lot of scientific and medical knowledge not accessible to modern researchers. Also he doesn't bother remembering all the heroes he's fought over the centuries. 

However, he still remembers many of the historical figures he's met, his origins, and so on.
