They say it is never too late. And the saying seems true when it comes to going for a walk, as experts have found a daily stroll that it could protect from many chronic diseases.
According to the US study, just a little light exercise can stave off heart failure, heart disease, stroke, diabetes and even Alzheimer's. And it is never too late to start. Stepping up exercise in your 50s can have major long-term benefits, Daily Express reported.
People who increased their fitness by just 20 percent in the middle age reduced their chances of developing the chronic diseases even decades later by 20 percent.
In fact, introducing a gentle walk, housework, gardening or DIY (do it yourself) into your daily routine from the age of 50 can cut the risk of developing these deadly illnesses at 65.
Jarett Berry, a senior author of the study, said: "We've determined that being fit is not just delaying the inevitable, but it is actually lowering the onset of chronic disease in the final years of life."
Researchers assessed the fitness levels of people in midlife and then followed them up 26 years later.
Researchers at UT Southwestern Medical Centre in the US city of Dallas, studied data of 14,726 healthy men and 3,944 healthy women of an average age of 49, enrolled in the Cooper Centre Longitudinal Study, which keeps medical records from over 40 years.
