A new study shows most people in the Yass Valley are living well into their 70s and 80s.
The report from the Australian Institute of Health and Welfare found the average age people lived until was between 78 and 82 from 2013 and 2017.
The local life expectancy is about on par with that of Goulburn Mulwaree but higher than the Upper Lachlan Shire.
The average age people lived until in the same period in Goulburn Mulwaree was between 78.5 and 80 and 74.5 and 78 in the Upper Lachlan.
However, the Mortality Over Regions and Time figures also worryingly showed the highest cause of death in the region was coronary heart disease (CHD), the common cause of a heart attack.
The cause represented ten per cent of all deaths in the region in the four years and affected men (12.5 per cent) slightly more than women (7.5 per cent).
People can reduce their risk of CHD with a healthy lifestyle including eating healthily and exercising.
The second biggest cause of death was dementia and Alzheimer disease (9.6 per cent), while the third biggest was cerebrovascular disease (CVD, 5.7 per cent), which is when the brain's blood supply is affected and can cause a stroke.
Both dementia and Alzheimer disease and CVD affected women more than men, with men more likely to die from prostate cancer - the third biggest cause of death among the gender.
