I think that our perception of time will change when we go to Heaven.
Right now, we don't how it feels to be immortal simply because we are not immortal. We see that things are changing around us all the time and things are decaying and withering away as time goes on. Plants and animals are dying everyday. But in Heaven, this is not going to happen. Our brains and bodies will never age and we can live forever and still be beautiful (no more second law of thermodynamics in Heaven perhaps).
Even time itself could be something different in Heaven.
Maybe that's why we don't understand how it's possible to live for eternity and yet not be bored because of living for so long. But ultimately, everything is good when you're close to the Creator.
