Just a hypothetical question posted for curiosity's sake.
Let's say in 20 years the secret to immortality is discovered. Everyone on this board suddenly becomes immortal through some revolutionary technique. No aging, no disease etc etc
Now jump forward 50 years, and science irrefutably proves that the afterlife exists in the form of eternal paradise, heaven & what have you for EVERYONE. (This is all hypothetical, I can't be bothered elaborating).
The question is: Would you give up your immortality and allow yourself to die, or would you carry on living an infinite lifespan in "this world"?
