ON STRANGER TIDES

Gibbs: Jack, I have to ask. You had the chalices, the water, the tear, you could have lived maybe forever?

Jack Sparrow: The fountain does test you Gibbs. But better to not know which moment maybe your last. Every morsel of your entire being alive to the infinite mystery of it all. And who's to say I won't live forever, hey? Discoverer of the fountain of youth. I have no say in it, Gibbs. It's a pirates life for me. Savvy!

(Pirates of the Caribbean - On Stranger Tides)

And who's to say i won't live forever?

I'm still here, but hey, you know i am always ready to go.
