Time is an interesting idea. When you have a project due or need to take care of things at work, you never have enough time. However quite the opposite when you are waiting on the results of a diagnosis or when you are waiting on the arrival of a family member that hasn’t visited in quite some time; time cannot go fast enough.
It’s a funny thing about time, it doesn’t change speeds. For that matter it doesn’t really exist. Humans figured out a measurement for time so they knew to do things at certain times of the year. Maybe it was for farming, meals or simply an understanding of how long we are on the Earth.
In all fairness they came close to the concept, but were not absolutely perfect, hence why we have a leap day every four years; to help us catch up with time that is lost.
We are the only things in the universe that cares or has any concept of time. The sun comes up and goes down according to its schedule. The flora and fauna live their lives without any concept of time.
It is fascinating that something that we created and have no control over, controls us so much.
