A little consistency goes a long way.

Number You Won’t Forget: 22 Minutes
When you think about adding years to your life, what do you imagine? Expensive supplements, and complex longevity protocols? That’s what gets most attention, but science paints a different picture that requires something much more affordable and habitual.
Just 22 minutes of daily physical activity can significantly reduce your risk of death and extend your life.
Researchers analyzed data from over 2 million adults aged 20-97 across four countries (United States, Norway, Germany, and Australia) to understand how physical activity affects mortality risk at different life stages. This massive study followed participants for an average of 10 years, tracking their daily movement through accelerometers and health outcomes over time.
People who engaged in just 22 minutes of moderate physical activity daily had significantly lower mortality rates compared to inactive individuals. But here's the fascinating part—while benefits appeared at all ages, they became dramatically more pronounced after age 60, precisely when many people start moving less.
The researchers believe this happens because our bodies become more sensitive to the protective effects of movement as we age. Exercise helps maintain muscle mass, bone density, cardiovascular health, and cognitive function—all of which become increasingly critical for survival and quality of life in our later decades. Think of daily movement as a compound investment: the earlier you start and the more consistent you are, the greater your returns.
And, there might really be something to the 20-minute threshold.
More than a year ago, we shared a different study on more than 12,000 people older than 50 who were studied for 12 years. All the participants wore fitness trackers to measure their sedentary time and movement.
Those who were sitting or sedentary for more than 12 hours per day had a 38 percent increased risk of death from all causes. But, that heightened risk of death completely disappeared for those who moved at a moderate intensity for at least 22 minutes per day.
If you want to get busy living, here’s your 22-minute movement prescription:
Start with what you enjoy: brisk walking, dancing, gardening, or playing with kids
Break it up: three 7-minute walks throughout the day absolutely counts
Focus on consistency over intensity: moderate activity beats sporadic intense workouts
If you're over 60, know that it's never too late to start—and the benefits might be even greater than for younger people
