I'm a reasonably healthy & active 56 year old, who lives on his own. I've considered getting one partly for the "fall alarm" thing. Someone on another forum I'm a member of is about the same age as me & had a massive stroke earlier this year, he wasn't found for several days which will have had major implications for his recovery. The fall alarm or the ability to call for help from a gadget on the wrist could be a lifesaver. As it is I'm very careful to have my phone in a pocket whenever I go up into my loft, just in case I fall or put my foot through the ceiling.
