Treadmill Keeps UK employee Fit

Kathryn Cunningham has a desk job at the University of Kentucky. But that doesn't mean she's stationary all day. She walks at her desk. Cunningham spent about $2,000 on a treadmill desk, which she has been using since moving into her tiny one-person office in the UK Science Library last fall. She compares her daily desk walk, which can be 3 to 7 miles a day, to the kind of challenge involved in having a class with hundreds of students, yet making sure that each one stays focused.
