Time is interesting... the way we measure time, our days and our life is built out of estimates, we all se and feel time different depending on our situation In life.
A stars lifespan can vary depending on its size and mass in between 10 billion years down to 10 million years, just as our life can vary just as much but in our timescale.
In another dimension, 10 billion years can be as a blink of an eye in our reality....
