New research shows that while people are waiting longer to retire, they experience health-related limitations at younger ages than previous generations did. “We found that younger cohorts are facing more burdensome health issues, even as they have to wait until an older age to retire, so they will have to do so in poorer health,” Robert Schoeni, a University of Michigan economist and co-author of the study, said in a statement. The researchers found a significant correlation between the age at which health limitations set in and educational level, with those who did not complete high school experiencing a much higher percentage of limitations than those with a college education. —J.B.
Food expiration labels that read “best by” often confuse consumers. Does “best” mean throw out after this date? Or does it mean it’s safe to eat two or three days past the date? Thanks to the innovation of researchers at Clarkson University in Potsdam, N.Y., such labels may soon become obsolete. The researchers developed a low cost smart label that can detect color or electrical changes in food that signal when the quality of the food is deteriorating. —J.B.
