Liam Elkind's big heart and his break from college was a highlight of 83-year-old Carol Sterling's week. The retired arts administrator has been sheltering at home during the coronavirus outbreak, unable to shop for herself. Yearning for some fresh food, she found the 20-year-old through their synagogue, and soon he showed up at her door with a bag full of salad fixings and oranges. Elkind, a junior at Yale, and a friend, Simone Policano, amassed 1,300 volunteers in 72 hours to deliver groceries and medicine to older New Yorkers and other vulnerable people. They call themselves Invisible Hands, and they do something else in the process - provide human contact and comfort, at a safe distance, of course. Elkind and his fellow volunteers take the name of their project from their vigilance in maintaining social distance from the people they serve, and their meticulous care while shopping and delivering. Grocery and pharmacy orders are placed on the Invisible Hands website. It's gone from extremely casual to extremely operational very quickly," Elkind said. "This is one of those times when I remember that New York is such a small town, and people are willing to look out for one another and have each other's back." Now, Elkind said, volunteers have offered to extend Invisible Hands to Boston, Los Angeles, San Francisco, Washington and London. "It's been really exciting just to see that amount of interest and how many people there are in this world who want to do good and are looking for ways to do that," he said.
