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.
Health is homeostasis. Homeostasis is an internal feedback system that stabilizes and balances our body chemistry, so that our organs work smoothly and efficiently with each other. Sickness is the disruption of homeostasis, which doctors treat with medicine. But medicine adjusts one homeostatic mechanism by disrupting another, which leads to more sickness and more medicine. This is why medicines are so profitable, but have so many side effects and adverse reactions. So healthcare should minimize medicine and maximize holistic factors, such as lifestyle, diet, exercise, education, recreation, and relationships.
