This is a follow-up on my post, The Maximum Human Life Span and Conjecture on Step Counts to Get There (15,000 Steps a Day). According to this research:
“By analyzing data on tens of thousands of people across four continents compiled between 15 existing studies, a team of researchers has now landed on a more comfortable figure: the optimal number is probably closer to 6,000 steps per day, depending on your age.”-Mike McRae, “Scientists Identify The Optimal Number of Daily Steps For Longevity, And It’s Not 10,000.” Science Alert.

This is a meta-analysis, which means it’s probably largely useless. But, it might be a good minimum level of steps to consider. Add in a weighted backpack, or rucksack, and it’s probably good, minimum advice.
