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.

I wish to mention that my half a century of running in the tree lined streets of Colombo, Sri Lanka or under the scorching desert sun of Riyadh, Saudi Arabia or in the air conditioned gymnasium in Atlanta, USA never needed extra electrolytes, proprietary drinks etc.
