Walking can literally add years to your life, and incorporating walks after meals can improve all manner of chronic metabolic disorders.
Hardly news, the body of research on walking was augmented with another study which took place in 2003-06 but whose results were only just published recently, showing that people who took 8,000 steps per day had a 51% reduced risk of death than those who took 4,000 steps per day.
Furthermore, as uncountable scientists in the past have confirmed, the study found a cumulative, dose-dependent effect on the person, as those who walked 12,000 steps or more had a 65% reduced risk of death.
The study consisted of about 5,000 participants who wore pedometers for three years, and whose circumstances of death were monitored by the scientists.
The science is quite clear: walk and live longer; exercise and live even longer.
