Can time really be wasted?  If it can be wasted, it can be collected and traded.  
But I cannot touch it, or smell it, or see it or hear it.  
I can feel it in an intangible sort of way.

In the way the heart feels the absence of love; tearing with every beat
In the way our bones can feel the mileage; creaking with every step

I cannot feel it within the hour or the day or even the week.

I can only feel once it has passed and I am already weak.
