'Superagers' reveal how to stay sharp as you get older

A 101‑year‑old Canadian violinist Morry Kernerman exemplifies the “superager” cohort—people over 80 who retain memory of those in their 50s. The SuperAging Research Initiative, led by the University of Chicago and headed in Canada by Angela Roberts of Western University (London, Ontario), is enrolling 500 participants across North America. Preliminary findings from MRI and post‑mortem analyses of 24 superagers versus 12 controls show slower brain shrinkage and fewer Alzheimer‑type changes. Three lifestyle pillars—meaningful hobbies, regular moderate‑to‑vigorous exercise (average 36 min/d), and strong social ties—correlate with better cognition. Canadian Statistics show only 46 % of adults meet activity guidelines, highlighting the significance of these behaviors in aging. Kernerman attributes his longevity to music, exercise, and teaching abroad.
