I picture heaven as one of those places where after the first like... thousand years, you'd get incredibly bored and just sleep 18 hours a day. You'd wake up for a little bit, realize how bored you are, and go back to sleep. Heaven is full of countless generations of sleeping people.

Plus, if you have reached heaven, your life is over... in more than way. For many, reaching heaven is the penultimate goal, and life as they know it is but a proving ground. So once you get there, you'd be so utterly content with your situation, that you would never bother doing anything every again. Complete and utter contentment means the end of personality, of action, of everything that defines a person. We exist to improve ourselves, to overcome obstacles in every day life, and work towards higher goals. If there are no problems, no obstacles, no goals, then there is literally nothing.

And Oddhunter, you're right. The texts documenting Jesus and his deeds are what encompasses the bible today (well, some of them), but not all of the individual components were wholly religious or biased, though their subjectivity is still highly debatable.
