Although it's been closed as a duplicate question, How did Albus Dumbledore get so old and remain so functional? got me to thinking. J.K. Rowling has made it expressly clear that there is no magic that can bring back the dead as they were in life (There are the Inferi, but Inferi are only creepy reanimated corpses.).
JKR has also told us that witches and wizards have longer life spans than Muggles, so perhaps there might be some genetic component in wizards that has to do with longevity.
As far as magic goes, though, aside from the Sorcerer's Stone and Horcruxes¹, are there any magical means by which to delay death in Potterverse?
Spell, potion, transfiguration ... I'm interested in any form of magic that would help extend a wizard's natural life. I'm looking for an answer based on canon sources, such as the Harry Potter books, interviews with J.K. Rowling, or Pottermore. Barring a direct canon answer, subjective answers in the spirit of canon are welcome.
¹I almost posted this question with no references to Horcruxes! I'll be very embarrassed if I've missed something else as obvious as Horcruxes!
