The original topic is about human and why you would continue to be immortal.

To continue for the sake of existing isn't a very good reason. It's like a mother being correct because she says she is. If the human existence if only to exist, you can easily stop thinking that it's necessary to exist and take all point out of existence, like OMB has done. It's in our genetic make up, but we can override it and refuse to continue procreation.

So existence relies upon itself to answer itself. It's kind of like the Bible, how the only way to answer how it is right is to quote the object in question.

When you're faced with a paradox, all you can do is pick a side and realize neither is wrong.
