I used to have a "medical alert" necklace that was part of my home burglar alarm system when I became afraid of falling when working out in my yard while my husband was at work. The signal only went as far as my mail box, which didn't help me if I wanted to go for a walk around the block or to the park. I used to be an independent person, and enjoyed walking for exercise. I read about MobileHelp and decided to give it a try. What freedom! My husband and I went for a weekend away and were so delighted it works wherever we go. I am diabetic and have mobility problems now, and was getting more and more tied to the house. With my MobileHelp "buddy" in my pocket, I feel safe to go out and do things on my own again!
