You never know though. Very unlikely but someone might find a way. Which sounds terrible. For a high school class I wrote a story about a guy that became immortal, long short story even shorter really sucked when the sun disappeared.To quote DOA by the Foo Fighters:
Nevermind there's nothing I can do
Bet your life there's something killing you
It's a shame we have to die my dear
No ones getting out of here, alive.
