LONDON (Reuters Life!) - Most Britons are "all talk-no action" when it comes to health and wellbeing, according to a survey for the British state health service.

Nearly half (46 percent) of 2,047 adult respondents to a survey from National Health Service's new online NHS MidLifeCheck service said they needed to think more about leading a healthy lifestyle.

A nearly equal number of people (47 percent) admitted they spend a lot more time talking about getting healthy than actually doing anything about it, and a third of adults (33 percent) say they wouldn't know where to start.

Women own up to being the worst offenders with one in two (48 percent) of the 45-64-year-olds surveyed saying they are more inclined to give advice about being healthy than take it (31 percent for men of the same age), the NHS said.
