Nilofer Merchant suggests a small idea that just might have a big impact on your life and health: Next time you have a one-on-one meeting, make it into a "walking meeting" -- and let ideas flow while you walk and talk.
Having recently received a FitBit and while I knew I was spending a lot of time sitting, I figured my three days of running would compensate. Not even close. Now I am trying to figure out how to walk more. Nilofer's idea is a good start.
