Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles.

The survey should have also included the number of people who take up 30 minutes of moderate exercise at least 5 days a week. Since 1974 the number of people who are in occupations which involve physical work has definitely declined. There is also increased awareness of the need to exercise which has far reaching effects on the life of individuals who have metabolic and cardiovascular illnesses.
