First of all, my sister and I are extremely different in most respects. She is highly social whereas I am very introverted, and her interests are mainly in the realm of shopping and gossiping (whereas I have been a science / computer nerd practically my whole life).
Interestingly, though, my sister is in total agreement with me that death is a bad thing, and similarly unable to placate herself with notions of an afterlife (neither of us think it's anything one can really bet on). We are so radically different in so many ways, and did not relate to any considerable extent while growing up, and yet now we are converging on the notion of indefinite life and life expansion. I am just wondering if there is possibly some sort of neurological / biological predisposition to being able to think seriously about the notion of immortality. I have read studies showing that some people's brains are more "wired" for such things as religion...could it then be possible that the opposite is true? That some people's brains are "wired" to resist various cultural memes?
