either way your completely unaware of either, so I don't think it really matters. From your own perception you are simple living life, and should be appreciative of the opportunity to do so.
not necessarily. you're aware of the possibility of its truth and how it could be true. you also know certain things will likely not change about your general being, like your disposition or sense of humor, assuming you don't hit your head in a weird way. would the thought of this possibility change how you live at all? if you thought each action you take you might have to repeat for eternity under the same circumstances, would you act the same way?
Yes, you are aware of the possibility, but only that its possible. So regardless of whether or not its happening, you wouldn't know, there for, it should not have an effect on you, because it is not a truth. (or at least it cannot be proven)
And given what I just said, I disagree that one would actually "know" that certain things would not change about yourself, because you dont know that you've got more then one life in the first place.
And even if you did know somehow know that you would be repeating for eternity, I don't think it should effect how you live. Because you may know that your stuck in an eternal cycle, but your not retaining any memories from the previous lives, so I cant see someone saying "Well, beings im gonna get re-incarnated im finally gonna go ahead take up cliff diving like i always wanted. Who cares if I die, I have infinite lives. "
Even though you'd be recycled eventually, and start over, what good what it be, you wouldn't know the difference, as far as your conscious memory goes, this is your first and only life.
ya digg?
Just throwing this last part in though -
Given an infinite amount of time, everything that can happen in the universe, will happen.
So essentially, if time can truly be infinite, then infinite versions of you will end up doing everything that possibly can be done.
