If you're a little overweight and you're aged 70 or more, you'll likely to live longer than your skinnier counterparts. Being overweight seems to aid longevity when you reach the age of 70, and your chances of living until the next decade are greater than for those whose weight is normal. Researchers from the University of Western Australia made the discovery when they reviewed the health records of 9,200 men and women aged between 70 and 75. They found that people who were overweight, according to the Body Mass Index (BMI) measure, were 13 per cent less likely to die in the following 10 years than people whose weight was normal, or healthy. The researchers say that health advice for older people needs to be revised - as does the BMI measure, which needs to allow for people's age.
