If I walk 6 miles, that’s 12,000 steps for the day. Other studies indicate that the more miles walked the better but I assume there’s a limit up there somewhere.
Another recent study shows that the faster you can comfortably walk is an indication of your general or overall health. My fastest comfortable pace is 3 miles per hour which, according to the studies, is very good for my age and a predictor of several more years of productive life. Of course that’s assuming a healthy life-style otherwise.
So, in order not to become obsessive/compulsive about exercise, I’ve concluded that 6 miles every day at a pace of 3 MPH is reasonable and my best hope of leading a productive life for most of the years left to me.
By the way, and for your information, I copied this from the internet:
"The origins of the 10,000-steps recommendation aren't exactly scientific. Pedometers sold in Japan in the 1960s were marketed under the name "manpo-kei," which translates to "10,000 steps meter," said Catrine Tudor-Locke, director of the Walking Behavior Laboratory at Pennington Biomedical Research Center in Baton Rouge, La. The idea resonated with people, and gained popularity with Japanese walking groups, Tudor-Locke said. [The Best Pedometers of 2014]” (http://www.livescience.com/43956-walking-10000-steps-healthy.html)
