About this trial
Considerable heterogeneity in the aging population has been observed. The exceptional longevity of individuals reaching 100 years old, so-called centenarians may be an example of life-long healthy aging, or added years may be spent in poor health with decreased physical and cognitive functioning. Current knowledge of the aging experience and the trajectories of physical and cognitive decline across various age groups are not well-understood, yet crucial to prevent spending added years in disease. Hence, the study objective is to develop the metabolic profile associated with aging-related disorders measured as the incidence of impaired functional capacity, cognitive function, and/or well-being.
