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.
It is quite possible that, as well as the effects of recent reductions in NHS funding, some of the reduction in life expectancy is a cohort effect. People who had wartime and postwar experience of food rationing are now over 70. The following generation, growing up in the 1960s were the first to be exposed to hyperprocessed food and the car as the principal method of transport. We can expect this to deteriorate as poor diet and reduced exercise increased as issues leading to the growth in childhood obesity now. As well as needing increasing resources to managing chronic diseases we must campaign to reverse our obesogenic society. This is not about healthcare as such, though public health professionals expressed concerns before they were decimated in the UK. We should also campaign for safer walking and cycling, facilitating healthier diets, and the other changes in society that our students protesting against climate change would also support.
