The research, which looked at those who had lived beyond 90, identified modest alcohol consumption as one of five key factors linked to a long life.
The research, which started in 2003 and was led by Cal neurologist Claudia Kawas, tracked 1,700 people who are in their 90s and examined daily habits on longevity.
The 90+ study had participants being visited every six months by researchers who performed neurological and neuropsychological tests. Dietary information, physical activities, medical history and medication were also factored into each study. The difference between these two examples, however, is the amount of alcohol involved, which is also an important point in this latest study on living a long life.
Researchers discovered that subjects who drank two glasses of beer or wine a day were 18% less likely to experience a premature death, The Independent reports.
Dr Kawas said, 'I have no explanation for it, but I do firmly believe that modest drinking improves longevity'.
"The more people outside of your". And drinking about two cups of coffee a day lowered the risk by 10 percent compared with the nondrinker.
"It's not bad to be skinny when you're young but it's very bad to be skinny when you're old", stated Kawas.
Even more surprisingly, the study found that being a little overweight - but not obese - could also help you live to a ripe old age, cutting the risk of premature death by 3%. Both are more common in women than men.
For some people, "living past the age of 90 and maintaining a healthier overall wellbeing in old age could be related to their genetic makeup", says The Indepedent. Among those with dementia, half do not have sufficient neuropathology in their brain to explain their cognitive loss.
Health experts have claimed that drinking one or two glasses of beer or wine each night could actually prolong your life.
"The sad thing is, we've added more years than we've added quality", Kawas said at the Austin conference.
