I started it for medical reasons. Dr. said I needed to walk for exercise when I was diagnosed with Type 2 diabetes. Well, I can't walk, just for the sake of walking, so got a DFX 3 years ago and the only thing stopping me now is it feels like I'm getting stabbed in the lower back when I walk or stand (L4 thru L7 problems like Lowbatts). Will know later in week if surgery needs to be done. Fortunately, the ground is frozen on the tundra of Minnesota, so I hope this gets taken care of by the thaw. The history and the finds and the mystery are great also.
