I always felt this was true...but must move more during the work day

Get off your behind!
I do try and walk around the office instead of sitting all the time but it's hard. I used to exercise on the stairs at 2pm but now that I do it in the morning I should work in a few sets of stairs in the afternoon as well. The above article doesn't explain all the possible reasons why sitting is bad - and how to mitigate them...perhaps the original study has that. Any number of risk factors could be at play...but it seems pretty obvious that the human body was not meant to sit in one position for hours on end.
