LONDON - Britons, it seems, are not older and wiser when it comes to drinking - a survey has found that those over 30 are no more sensible than younger boozers.

The survey for the "Know Your Limits" campaign found that a third of people aged 30 to 50 admitted that, on at least one occasion in the last year, drinking too much had ruined a night out or a family event.

Half also said excessive drinking had given them a hangover which left them unable to function properly the next day.

"You often hear people saying they feel worse after drinking the older they get," said GP Dr Sarah Jarvis.

"As you age, the body isn't as good at dealing with alcohol. This survey shows that many people find it difficult to stop once they've started drinking. The answer is easy - don't start if you think you may lose control."

According to the survey, 44 percent of those in the 30-50 age group admitted they had not stuck to their limit - the amount they knew was too much for them and would regret the next day - compared to 40 percent of 18 to 29-year-olds.

Health officials have warned that slightly older people, who drink regularly at home, could be risking serious problems.

NHS admissions for those aged between 35 and 49 with alcohol-related conditions, such as coronary heart disease and liver problems, have soared in recent years while drink-related death rates for women almost doubled between 1991 and 2005.
