M 72. Back problem and hip problems so I walked very little. This pushes me. Some days I only walk 3, 000 steps some 6, 000. For me that is huge. I bet it was closer to 1, 000 before. Some time I feel it vibrate and it tell me I need 250 steps that hour so I do it. What 250 steps? Get an inexpensive one. It might just save your life.
