Summary:

When Darth Vader dies he has the unfortunate luck to wake up in his twenty year old body, which incidentally consists of an extra arm, two extra legs, a lack of burn scarring, functioning lungs, and hair.

For all that he'll probably come to appreciate it later, coming to in a healthy body when you haven't felt a gentle touch in twenty-odd years isn't exactly a pleasant experience.
