Lucky you, you get to put the afterlife off for a little while then. [Dipper shrugs.] There are a lot of worlds. And you're not the only person who'll be dead if they go home. But I'm not anywhere close to dying. [Yet. If what Ford's said is true he isn't sure how long he'll have, but at least he knows it's more than seconds.] And I have people here from the future who can confirm.

Also? Some people from those other worlds haven't heard of it. So it's always worth checking.
