I made up this rhyme back when I was a young man...I'm 71 now so maybe I should think about writing a concluding verse, or maybe a continuing one in case I have another 20 years in me (unlikely). I still like it and once drew a thoughtful cartoon to accompany it.
When I turned round, the marching years
Had covered my furry chin with beards.
When I looked back at the playground there
were beautiful girls with golden hair.
When I ran home along the street
and all the blood in my heart did beat,
A young man in my limbs was leaping
who left young Tom behind him, sleeping.
