Why Do I Run (poem)

WHY DO I RUN?
'TAIN'T NO MYSTERY--
WANNA HAVE A GOOD MEDICAL HISTORY.
DOCTOR TOLD ME
RUNNIN IS GREAT--
HELPS THEM BLOOD CELLS CIRCULATE.
GREAT FOR THE LUNGS,
GREAT FOR THE TICKER
CAN'T NOTHIN' GETCHA IN BETTER SHAPE QUICKER.
FEELS SO HEALTHY,
FEELS SO SWEET
PUMPIN MY ARMS AND FLAPPIN' MY FEET.
MOLDIN' MY MUSCLES,
FIRMIN' MY FORM,
PANTIN' LIKE A PACK MULE,
SWEATIN' UP A STORM.
KEEPS ME YOUTHFUL,
KEEPS ME LOOSE,
TIGHTENS MY TUMMY AND SHRINKS MY CABOOSE.
BEATS BEIN’ SLUGGISH
BEATS BEIN' LAZY--
WHY DO I RUN? MAYBE I'M CRAZY!
