Wise words. I also invested in a watch with "fall protection" because I walk for miles, often alone. When I fall (as I do; I practice balance + crumpling rather than tensing) it says, "Are you OK?" and if I don't assure it I'm fine it calls the paramedics, because it knows where I am. Pretty spooky. So far I've always been able to shut it up before it embarrasses (or saves) me.
