Doesn't Bekka wear one of these? The one on the Andromeda scifi series, I mean!
Apparently this one is aimed at rescue workers and specialty uses. I think I read somewhere that it even has capability to identify lack of movement for a period of time to help id rescuers that are in trouble.
Personally, I'd like one, but it isn't exactly socially acceptable at the moment, is it? Can you imagine the looks? How about in that meeting in the executive board room with the officers of your company?! Oh my! You might just as well wear blue superhero tights!
