A lot of people -like office workers or even radio personalities- tend to spend a lot of their workday sitting.  And we certainly have heard a lot of recent medical information about the health dangers of sitting for extended periods of time.  In fact, to combat the routine it's too easy to slide into, some sedentary office workers set alarms or use fit bit type technology to remind them to get up and move about once in a while.

The electronic reminders are a good idea, especially when you realize that long stretches of sedentary behavior have been linked to changes in part of the adult brain that's critical for - memory.

University of California, Los Angeles (UCLA) researchers published finding in the journal  PLOS One, showing sedentary behavior linked to the thinning of the medial temporal lobe, a region of the brain involved in the formation of new memories and can be a precursor to cognitive decline and dementia in middle-age and older adults.

Fox News reports the findings are preliminary and notes the study doesn't prove causation.
