In addition to the other well-documented benefits of drinking a moderate amount of alcohol, the Harvard University researchers suggest there's a clear advantage to having a drink on a regular basis rather than just at weekends. Having one or two drinks nearly every day of the week makes you 28% more likely to age more successfully, they claim. And that means avoiding serious illnesses as you get older, including heart disease, cancer and memory problems.
One of the reasons why that might work is if you have just one or two drinks a day, rather than all your alcohol over two days at the weekend, you won't suffer any ill-effects caused by binge drinking.
But before you crack open another bottle, researchers elsewhere have a warning for people who mix alcohol with energy drinks. According to a study due to be published early next year in the journal Alcoholism: Clinical & Experimental Research, young people who knock back energy drinks are more likely to become dependent on alcohol, thanks to the fact that the caffeine in energy drinks masks the effects of alcohol. In other words, thanks to the caffeine you don't think you're getting drunk - so you drink even more.
