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.
Yes, by all means publish research that "could improve our health", but why not say so, rather than waffling about research that "has the potential to impact on" health? Something that "impacts on" health could just as easily make it worse.
It is a general trend in English usage (American more than British) that the noun "effects" is being replaced by "impacts", and the verb "affects" is being replaced by "impacts on". (1) It does not make the language any clearer, and dilutes the specific meaning of impact (forcible contact).
