exercise

so I am in the middle of reading a report,  by the health commission,  and it states that only 1.3 million people walk to work, the rest use other methods like tube, bus etc.
the problem is with the obesity epidemic rising and rising it is important that people keep active.  Unfortunately from these studies we are not reaching the minimum steps of 10,000 a day. 
if we all use our car less, or find other ways to move it would definitely reduce the chances of getting heart disease.
