Hi, I'm Fred, I'm a builder. I work on a building site and I'm not allowed to have my Phone with me. I do leave it nearby in the porter-cabin. Just as well, because the other week when everyone had left and I was doing my final inspection, I lost my balance in the mud and badly twisted my knee. I couldn't walk. It was agony. Luckily, my Handi SOS sent my alert to my work colleague who was just 10 mins away. He came back and offered me some much needed assistance.
