Rapid responses are electronic letters to the editor. They enable our users to debate issues raised in articles published on thebmj.com. Although a selection of rapid responses will be included online and in print as readers' letters, their first appearance online means that they are published articles. If you need the url (web address) of an individual response, perhaps for citation purposes, simply click on the response headline and copy the url from the browser window. Letters are indexed in PubMed.
The world is full of homeless people. They live in hospitals, prisons, shelters, shacks, and on the street. We try not to think about these people, because they remind us that our lives are not that secure. We assume that homeless people are derelicts who don't care about themselves, but this is not true. Homeless people are professionals, average people, senior citizens, and runaway teens, who are often helpless to change their situation.
Homelessness is often the end result of malnutrition and addiction. As people become homeless, their diet and their addictions become worse. Homelessness and addiction are a vicious cycle that society can't correct. It's ironic that society promotes the sale of addictive substances but ignores the consequences of addiction. Society must choose between human health and economic health. Society must choose between an economy based on nutrition and health, and an economy based on addiction and sickness.
