Want to increase your own healthspan? The genetic die may be cast, but it’s still possible to add healthful years with lifestyle changes. Two recently published studies, one on U.S. veterans and one on U.K. civilians, help quantify by how much. Each study monitored nearly 300,000 people over a decade, tracking their lifestyles and looking for payoffs to healthy habits. The takeaway: small changes can have big effects, and big changes can have huge ones.

It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
