Time and tide wait for no man.
How many times and how much time has this subject been debated over the centuries and we are still no closer to the answer, but there is no doubt that it will continue for time immortal.
The concept of time was created out of observations of nature and the universe, secondary to that, time was then used to manage activities to enable an ordered life via routine and to study actions and predict/manage/achieve results.
Time is relative, a fly lives a lifetime of approx 15 to 30 days, human life average approx 75 years, earth's axial rotation 24hrs, Jupiter's rotation 9.9hrs, an un watched kettle boils quickly, a watched kettle appears to take a long time. How much time do we take helping and caring for others?
Where is the depot that all wasted time is stockpiled and where is the safe where all the saved time is stored?
There are 3 states of time, resting, constructive, destructive, you have a choice of 2, its up to you which ones you choose.
