re: If you quickly walk 6-8 miles a day would you consider that a worthy work-out?

Curious, but what do you do that requires walking 6-8 miles a day?

I used to have a job in Katy that required being on the phone non stop all day long inside a cubicle. I was so exhausted that I survived on coffee and trying to to fall asleep in traffic on the drive back to midtown.
