Even Casual Walking for an Extra 2 Minutes Each Hour May Help Prolong Life

In an observational study that followed participants for an average of just under 3 years, a “trade-off” of sedentary activity with low-intensity activity was not beneficial, but a trade-off of 2 minutes/hour of sedentary activity with an equal amount of light-intensity activity was associated with 33% lower risk of dying in the general population and a 41% lower risk of dying in the individuals with chronic kidney disease.

60 = 50: New Study Reveals Increases in Life Expectancy Reflect Slower Population Aging

Everyone knows that 60 is the new 50. But now, Warren Sanderson, a Professor of Economics at Stony Brook University, and Sergei Scherbov, a project leader at an Austrian research institute, have written an article about future population projections for Europe up to the year 2050 published in PLOS ONE, which shows that, counterintuitively, population aging is slower when life expectancy increase is faster – 60 really is the new 50.
