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.
I read the BMJ Confidential most weeks: am so pleased to see the response "I might have done" to the question "Do you have any regrets about becoming a doctor?" Most of the medics you interview are at the top of their field (they have to be, to be of interest to the BMJ!) and usually respond with "no regrets". It is heartening and encouraging for some of us who are not so enthusiastic about medicine to read that there is a niche for almost anyone in medicine! I do believe this is true.
