Tired While Retired

When younger, I would stay up late And drink a lot of wine, But nowadays, with half a beer, I hit the hay at nine. My teaching days, once filled with work, Plus quite a long commute, Would wipe me out for reasons that Nobody would dispute. Yet, now retired, I walk three miles And pass the extra time With reading, crosswords, phone calls And, of course, my daily rhyme. Though in the afternoon, I feel Exhausted, truth be told, Except that now, my main excuse Is that I’ve gotten old.
