E. One of the startling realizations that I had while researching this column is that anybody could become like a homeless person--all it takes is a traumatic (创伤的) brain injury. A bicycle fall, a car accident, a slip on the ice, or if you're a soldier, a head wound--and your life could become unrecognizable.James O'Connell, a doctor who has been treating the most vulnerable homeless people on the streets of Boston for 25 years, estimates that 40 percent of the long-term homeless people he's met had such a brain injury. "For many it was a head injury prior to the time they became homeless," he said. "They became unpredictable. They'd have mood swings, fits of explosive behavior. They couldn't hold onto their jobs. Drinking made them feel better. They'd end up on the streets."
F. Once homeless people return to housing, they're in a much better position to rebuild their lives. But it's important to note that housing alone is not enough. As with many complex social problems, when you get through the initial crisis, you have another problem to solve which is no less challenging. But it is a better problem.
G. Over the past decade, O'Connell has seen this happen. "I spend half my time on the streets or in the hospital and the other half making house calls to people who lived for years on the streets," he said. "So from a doctor's point of view it's a delightful switch, but it's not as if putting someone in housing is the answer to addressing all of their problems. It's the first step."
H. Once in housing, formerly homeless people can become isolated and lonely. If they've lived on the streets for years, they may have acquired a certain standing as well as a sense of pride in their survival skills. Now indoors, those aspects of their identity may be stripped away. Many also experience a profound disorientation at the outset. "If you're homeless for more than six months, you kind of lose your bearings," says Haggerty. "Existence becomes not about overcoming homelessness but about finding food, begging, looking for a job to survive another day. The whole process of how you define stability gets reordered."
I. Many need regular, if not continuous, support with mental health problems, addictions and illnesses--and, equally important, assistance in the day-to-day challenges of life, reacquainting with family, building relationships with neighbors, finding enjoyable activities or work, managing finances, and learning how to eat healthy food.
J. For some people, the best solution is to live in a communal (集体) residence, with special sevices.This isn't available everywhere, however. In Boston, for example, homeless people tend to be scattered in apartments throughout the city.
K. Common Ground's large residences in New York offer insight into the possibilities for change when homeless people have a rich array of supports. In addition to more traditional social services, residents also make use of communal gardens, classes in things like cooking, yoga, theatre and photography, and job placement. Last year, 188 formerly homeless tenants in four of Common Ground's residences, found jobs.
