Re: The basic idea may be sound
Most of my elderly relatives use Life Alert. It has extended the lives of several of them, despite most of them being cantankerous old farts who insist on living alone and taking care of themselves in their old age. My Great Aunt, who is well over 100, has had the service for over 25 years, after seeing the Dr. C. Everett Koop commercials on TV in the early '90s. It has saved her life a handful of times.
