Listen to Story Sally Froelich, aged 95, is one of 600 participants in the SuperAgers Family Study by the American Federation for Aging Research. The study aims to recruit 10,000 'SuperAgers', defined as people 95 and older who are in good physical and mental health. Dr Sofiya Milman, a national expert on ageing, emphasised the importance of this study to understand what biology contributes to longevity.

The study also includes the children of the SuperAgers and the children's spouses who don't have SuperAger parents. "They are just as important as the SuperAgers because we need to draw comparisons in the frequency of the genes," Dr Milman told Healthline. Identifying these genes could lead to developing medications that mimic their effects, potentially helping more people live longer, healthier lives.

'SuperAger' Sally Froelich's lifestyle secretes besides genes for longevity are below: Eat a balanced diet: The 'SuperAger' said she eats three meals a day and doesn't overeat.

Avoid smoking and excessive drinking: Smoking increases the risk of premature death from heart disease or stroke. Moderate drinking can also shorten life expectancy. Maintain a healthy weight: Froelich's weight hasn't changed in 50 years, though she said her body has changed.
