I learned on 10 tv news that those who sit 11 hours have a greater chance for 13% cardio  disease, 20% increase in heart problems and 20% increase in cancer. WOW!  Have you added up how many hours you sit each day?  Yes this includes travel time.  This is a perfect time to get the pedometer you have been thinking about.  My husband and I each have a Fitbit.  It records your steps; calories burned and is a clock.  It keeps track on your computer and portable devices.  For hints on how to use and goals to set just give me a shout.
