I used to wonder about news stories about people falling into the gap between the subway and the platform. In most stations, the gap is less than a 3-4 inches. How could a person fall into that? And then yesterday, after a few weeks of nonstop news about deaths and injuries from gap incidents, I took a hesitant step out of the train in Times Square, as the guy in front of me slung his backpack onto his shoulder. A second later, I was knee-deep in the gap with my right leg. Ouch! Embarassment! But mostly…lucky. The man behind me shoved both his hands under my arms and lifted me out immediately.
