Time?

Time – as we know it, is our measure of past, present and possible future of our life. Our collective lives.

It is our map to make sense of existence, our compass to navigate through our lifetime.

It really doesn't mean anything. The days, the seasons remain relatively same in one's lifetime. The evolution, the minor tweaks in nature remain relatively slow. Things are either set in pattern or too slow to categorize in patterns. So, it is just a self-made concept, a tool really to count.

When did earth form? When did humans arrive? How old am I? How many years will sun last? What is our average lifetime? Time was the only way to answer such random, unrelated questions and make some/any sense out of them.

If I were to define time as:
Sunrise to sunset = 1 day
Sunset to sunrise = 1 day
10 such cycles = 20 days = 1 year
I will be much (MUCH) older than I am in current nomenclature

However, if I defined time as:
7 days (normal days) = 1 day
I would suddenly be transported to my childhood (SWEET!)

It is just that we stuck with one idea of time and ran with it. Also, we became too many (too many people) to have different systems. Globalization would take a giant step back if we had no consistent 'time' lexicon.

But, it is just a tool. There's no “time” running out. Things birth, they die. 'Time' doesn't stop... only means that nothing changes relative to our short lifetime. We can, if we want, think of our time as an infinite days and nights and months and years. No one can argue against it.
