For me, I have some reservations, but mainly for other, particularly younger people. I personally don't give a toss if any government sticky beak looks at my info....I feel I have nothing to hide from them or anybody else. I'm highly unlikely to work again in the future, and don't need any insurance. If someone wants to steal my identity, they won't gain much from me. I have a bunch of very complicated medical issues, and so if I collapse in a shopping centre whilst alone, or are hit by a bus, at least all my medical crap is in one place and is accessible. If I was to wear a Medic Alert bracelet large enough to have all the details on it, it would be the size of a dustbin lid!!!
