Why time seems to go by more quickly as we get older

The materialistic science explanation:

There are several hypotheses which attempt to explain why our perception of time speeds up as we get older. One idea is a gradual alteration of our internal biological clocks. The slowing of our metabolism as we get older matches the slowing of our heartbeat and our breathing.

Children’s biological pacemakers beat more quickly, meaning that they experience more biological markers (heartbeats, breaths) in a fixed period of time, making it feel like more time has passed.

Another hypothesis suggests that the passage of time we perceive is related to the amount of new perceptual information we absorb. With lots of new stimuli, our brains take longer to process the information so that the period of time feels longer.

The Alternatice Science explanation

We loose life force when we get older. This flow of energy is not in sync with the energy flow of the entire solar system. Therefore we perceive that time “flows away” instead that we flow with time.
