"71% reported they walked more than 10 miles a day at work."

So what? How far does a postman/woman walk? Are we getting up petitions against the postal service?

I've worked in a warehouse, and was on me feet all day, often going up and down ladders with armfuls of goods. I really enjoyed it.
PS I had a three-mile walk to get to work, and another three miles home. And often in the evening I'd go out dancing.
