In other words, we want to minimize the number of years that a person spends suffering while maximizing the total number of years. In fact, a study was done at Stanford that examined the risk factors and morbidity/disability in 418 adults over a 12-year period. People with fewer risk factors (people who had healthier lifestyles) experienced less decline than people with more risk factors. The conclusion? Age-related morbidity can be reduced and postponed with healthier lifestyles.
