Immortality would be a crashing bore and no religion has ever developed an attractive picture of it. I'd like to live a longer life - maybe live to 150 or perhaps a little more, but no one deserves to overstay their time.
Life as a disembodied spirit, as many theologies suggest we'll end up, would be profoundly pointless and makes no sense at all. It shows that childish wishful thinking is one of the foundations of religion.
Immortality should only be "a crashing bore" if you are a boring person.
But then again, if one is unable to get a handle on it while living what gives any assurance that one will do better with a dead brain?

Generally religions refer to the soul only as being immortal. The body and brain return to the dust of its origin.
This is incorrect as far as Christianity and Islam: the body and brain indeed return to dust, but are brought back from the dust into a form that will never become dust.
In fact, in Christianity, being a soul without a body is what's called "death".
