Sometimes time moves at a steady pace. And sometimes you can't stop that steady progression of life's enduring tempo.
This causes a thing called aging.
Age, according to a book of diction, is defined similarly to (or exactly as) the following:
1. To grow old
2. To mature, as wine, cheese, or wood
Life's tempo is turning me into cheese, essentially.
I am an immature cheese for the next half-handful of days.
