A difficult opponent, Old Man Time, 
In the end no mortal man can stand, 
No matter what the measures of the climb, 
He sweeps them down with swift and equal hand 
 
Without it nothing can exist, 
And with it nothing will, 
He likely has you on his list, 
Your features fit the bill 
 
Time attacks in many modes 
The universe around, 
Rock erodes and lead corrodes, 
To him our lives are bound 
 
And still I think I'll keep on fighting him, 
In this case it's not difficult to choose, 
For though it's inconceivable to win, 
I'll likely never know it when I lose
