If there are infinte universes/realities , wouldn't it be great if death in this dimension just meant that you skipped to the closest dimension in relation to the one you died in. In that dimension it would be a near death experience.
It is said that every choice you make there is another reality that exists the moment you decide. If I have an option of taking a left road and a right road and I take the left a parallel reality exists where I took the right road.
Just thinking about it, sometimes fun to make your own silly theories about stuff.
But then there is old age, what would happen then? This is a pretty heavy flaw.
