Research published in the British
Journal of Sports Medicine in 

00:00:06.321 --> 00:00:09.179 
mid-November shows that physical
activity brings greater health 

00:00:09.179 --> 00:00:10.608 
benefits than we think. 

00:00:11.128 --> 00:00:15.571 
Scientists assessed the activity levels
of more than 36,000 adults aged 40 and 

00:00:15.571 --> 00:00:18.648 
older in the US and
converted them into walking. 

00:00:18.728 --> 00:00:23.150 
It was observed that the least active
group only did the equivalent of 50 

00:00:23.150 --> 00:00:27.257 
minutes of walking, while the most
active groups could walk for about 160 

00:00:27.257 --> 00:00:29.468 
minutes, or nearly 3 hours per day. 

00:00:29.468 --> 00:00:33.683 
The results showed that the least active
group had a life expectancy that 

00:00:33.683 --> 00:00:38.222 
decreased by 5.8 years from about 78 to
73, while the most active group 

00:00:38.222 --> 00:00:41.788 
increased by 5.3 years, to an average
life expectancy of 84. 

00:00:42.328 --> 00:00:46.237 
Thus, if the most sedentary group added
111 minutes of walking or equivalent 

00:00:46.237 --> 00:00:50.448 
activity each day, they could extend
their life expectancy by up to 11 years. 

00:00:50.548 --> 00:00:54.643 
However, this is just a scientific study
based on a group of people and more 

00:00:54.643 --> 00:00:56.828 
specific studies will be needed to draw conclusions, 

00:00:57.268 --> 00:00:59.448 
But there is no denying that exercise has benefits. 

00:00:59.488 --> 00:01:02.488 
But there is no denying
that exercise has benefits.
