Falls are the leading cause of accidental deaths among people over the age of 75 and the second leading cause for those aged 45 to 75, according to the National Safety Council. There are also other medical emergencies such as strokes and heart attacks. Many elderly people live alone, but a medical emergency can happen when their spouse is away or even asleep. This is why it may be helpful to add medical alert functionality to your security system. Imagine a man having a heart attack in his mobile home, and having no way to call for help. Having a wireless medical alert transmitter could save his life.
