The concept of time has long been in existence from the very beginning.
Why would there be a beginning if there's no end? It doesn't quite make sense, right? Or does it now?
Time is the space between the beginning and the end.
Is it?
In high school, speed was defined as the time it takes to cover a distance. Does it now mean that time is the speed it takes to cover a distance?
If this argument holds any water, then the real currency of the world is time. Or am I getting ahead of myself here?
$100 today Vs $300 in 10months time. Which would you prefer?
A sense a bit of contraversy with yourself... Lemme help you.
Every year, countries try to show a positive growth in GDP. You don't think this depreciates the value of the dollar with time?
What you got for a dollar 3yrs ago would have added some cents to its value if not a few dollars.
So, which is the real currency, time or money? 
time is the real currency ....this piece takes me back to the movie "in time" and all it tried to tell us. wonderful writing.....thumbs up!!!!
Oh yeah, I remember that movie too. Thanks @cocothesie
