Observation on time

One can never truly measure time
It varies from day to day
The tree may seem long lived
Yet the rock one day is a mountain
Even among man
If stress rules a man of youth can look wizened
Yet a mature man who's lived carefree appears youthful
A true measure of time, it could be said, is experience
Two people of the same age will differ
One could never leave home yet age rapidly
The other could travel the world and seem younger for it
Time is fickle yet undeniably profound
It touches every thing yet nothing
One can never truly measure time
