"Sitting Disease": How do we prevent it?

Does convenience come with a price? These days you really don't have to do much exercise if you don't want to.  You can have almost anything delivered to your house (i.e. food and supplies).  Also, if you commute to a desk job or are a student there is a lot of sitting involved there too.  Think about it, many individuals get up and take either the bus or drive to school/work, they then sit in lecture or at a computer doing their work. Then they come home.  The setup isn't designed to include much physical activity.  There is so much sitting that researchers have labelled in the "Sitting Disease".
