Boston fire inspector Albert Arroyo, on tax-free disability since March (“totally and permanently disabled,” wrote his physician) from an unwitnessed on-the-job injury, apparently heroically overcame his condition and six weeks later finished eighth in the 2008 Pro Natural American bodybuilding championship. Said his lawyer, James Dilday, time in the gym was actually a way for Arroyo to get his mind off his depression at being forced to take early retirement at age 46. (A Boston Globe investigation in January found 102 firefighters with mostly questionable job injuries, taking full retirement, with some manipulating paperwork to retire at a higher grade than when they were “injured.”)
