Heck, I often live on my own for short periods and I'd jump at wearing one! My back can go out with no notice (yeah, okay, except the 2 - 3 weeks beforehand when I've been too lazy to exercise, but y'know what I mean) and on a couple of occasions I've been reduced to crawling about for 2 - 3 days, barely able to reach a tap for a drink of water. At my age, and because I work etc (and this only happens if I neglect myself) I wouldn't expect that kind of support, but get me to retirement unscathed and I'll be signing up asap, regardles of how otherwise fit I am. I totally agree it's an independence helper rather than anything else, it's surely not that much different to having a phone. People, eh? :-/
