Living beyond your expiration date

Creating original work (writing a book, making a scientific discovery, founding a company) is currently the only way to live beyond your expiration date.

(playing devil's advocate: having children?)

Living beyond your expiration date does not mean making history (it could, but it's extremely rare). It means people will keep on building on what you started. It may be for a few more months or decades or centuries depending on how useful/groundbreaking your original work is.

N.B. Like food you put in the freezer and decide to cook later, your work can be re-discovered many years after your death.
