Vital longevity is a strategy to extend lifespan while preserving function, or healthspan. As a result, patients find themselves enjoying more “good” years and delaying age-related frailty so they can continue to be active and engaged. Lifestyle medicine plays a key role in vital longevity by using evidence gathered from studying centenarians (people who live to be over 100) and applying the findings to everyday behaviours. Vital longevity also takes into account individual risk factors and supports patients in adopting proven strategies to live a healthy lifestyle now, so they can avoid many age-related diseases in the future.
