SLOWER, PLEASE: Study confirms that some people age more slowly. “People really do vary in how fast they age, and the divergence starts in young adulthood, a new study suggests. The researchers found that by the tender age of 45, people with a faster pace of “biological aging” were more likely to feel, function and look far older than they actually were. And that relative sprint toward old age began in their 20s. . . . It turned out that, indeed, people varied widely in biological aging: The slowest ager gained only 0.4 ‘biological years’ for each chronological year in age; in contrast, the fastest-aging participant gained nearly 2.5 biological years for every chronological year. And by age 45, rapid biological agers were already showing some health indicators normally associated with old age.”
