Well I never.

I have to say that it's been quite the eye-opener about how much better I feel after "only" walking a mile a day. For the record, that's about 20 minutes of very light exercise. I'm sleeping better and my back, which has been problematic for the past month or so, is giving me less grief.

I know that articles often say you don't need to be doing much, but it's different seeing it in action.
