[pct-l] I NEED to be walking!

[nosirreeb]

I've seen several articles recently that tell of the harmful effect of sitting for long periods, even for those who otherwise get plenty of exercise. Here's one from NPR (text and audio):   www.npr.org/2012/05/09/152336802/stand-up-walk-around-even-just-for-20-minutes

It inspired me to buy a Gymboss interval timer that I have set to go go off every 20 minutes as a reminder to stand up and move around a little. YMMV.
