NASHVILLE—Matt Terrell, 27, is a man overqualified for his job as a baggage handler. The two pleasures he derives from the day are his lunchtime joint and the math formulas he scrawls on the interior of plane baggage holds. He is a mathematical genius responsible for loading and unloading our traveling burdens. They see his work at Newark and Seatac and LAX and wonder “What in the hell…?” Terrell smiles with glee as he educates and confounds fellow baggage handlers in awaiting cities across the country. True bliss for a satisfied man…with a joint in his hand.
