That's very true Granny - it must have been much harder to quit smoking back when everyone was smoking in restaurants and airplanes and such! Now at least you don't have that constant reminder

Jase - The US government actually defines sedentary. If you don't move at all (stuck in a bed) that's not sedentary, that's bed rest. If you move around for general chores that is just counted as "ambulatory" but you are still in the sedentary class if that is all you do. So sedentary by definition are people who are ambulatory but who aren't getting at least a half hour of solid heart-raising activity every day.
So someone who is able to walk to the store is not on bed rest - but they are still sedentary if that is all they are doing for their activity. You have to be more active than that to get out of the sedentary category

Now that being said, if you walked a full half hour to work each way, then you should count that half hour each way as exercise, assuming you're walking at a nice clip. If all you're doing is walking to the car and getting into it, then that wouldn't count

That would just be "normal life movement" like rolling over in bed
