I just came up with an that Anakin Skywalker was a clone, who was genetically modified to age twice as quickly. A Cloning Corporation creates clones to sell for labor. He was created 32 years before A New Hope. Controversy over cloning causes the Clone Wars.
22 years before A New Hope, when he is 10, but is aged to look 20, he is a navigator on a spice freighter before being found by Obi-Wan and becoming a Jedi. Luke and Leia are born 20 years before A New Hope and their mother’s DNA makes them age normally.
Therefore by Return of the Jedi, Anakin dies at the age of 36 but he looks like he’s 72.
