There once was a man from Duluth

nearly 40 years old; past his youth!
But tonight with a smile,
he swam non-stop for a mile.
First time in his life - that’s the truth!

I swam a mile when I was 17 and again last summer, but never non-stop before. I know it doesn’t compare to real swimmers (it took me 45 minutes), but I’ve been swimming for less than a year. Plus i found two meaningful rhymes for “Duluth.“ I rock. : )
