On the Longest Tennis Match that Still Has Not Ended

Without question
a course for endurance occurs
on the blinding blades of grass
in between back and forth
of unending yield
for immortality means never change
a currency of perpetual birth
can only give rise to answer
with one more slide
into precipitant obsolescence
if one was not there to see
the sun set it will return
waiting for the clock to break again
we will keep the score on our skin
and run out of flesh real fast
