That's an excellent concern. Of course I have a pack full of test strips, meter, insulin, pen-tips, etc. but my fear is that someone might mug me when I'm "down" in public. This almost happened to me once when I tripped and fell -- I was instantly "prey" to some on the street, but a couple of guys intervened and helped me, thank goodness.
A tattoo can't be stolen, but I hate to be "marked" -- I'm holding out for a cure!!! ;0)
