The middle ab on the left (not my left, your left, if you are looking at me) is called Terrence. It’s a dignified ab. It tenses each time I read an op-ed article about global warming. The article’s point of view is immaterial; simply being reminded that I can do nothing to stop the horrific future of floods and catastrophe gives this ab a taut yank that lingers, burning calories in my well-creased forehead at the same time. Best to do right before bed, as the accompanying nightmares keep those abs pumping into the early-morning hours!
