We perceive time something like a stack of memories.
So the less new experiences you have,
the less likely you are to fill in those memories with interesting things.
Time does go by more quickly the older we get.
In the first few years of our lives
Anything we sense or do is brand new,
And many of our experiences are unique,
so they remain firmly in our memories.
As the years go by
we encounter fewer and fewer new experiences
both because we have already accomplished a lot and because we become slaves to our daily routines.
We need to try new things,
slow down the passage of time
and increase our happiness.
