Want to live forever? Science hasn't quite cracked that one yet, but a group of Harvard researchers has figured out how to give you the best possible shot.
For 75 years (and counting), researchers have been following the same 600+ people to determine what makes a long, healthy, and happy life. These studies, titled the Grant and Glueck Studies, are two of the longest longitudinal studies on health and happiness ever conducted, containing tens of thousands of pages of participant questionnaires, health records, brain scans, blood samples, journals, interviews with friends and families, and, of course, scrotum measurements.
With study participants now in their 80s and 90s, and many having passed away, the Harvard researchers have identified seven key factors to living as long as you possibly can (while not being a miserable prick the whole time). Sure, "seven secrets to a long life" might sound like a garbage "health" blog post. But unlike most "secrets," these have 75 years of Harvard research to back them up, so you might want to pay attention.
