Gargoyle and Wysi have got the right idea. Just be someone (or many) else.

I quite accidentally lose my card every so often and get a new one which should confuse them enough. Also, every so often we buy some bulk items for the church (Where Kelly works) and I use my card then. I hate to think how our database entries stack up against the norm.

Hey Leprachaun, I had a buddy once who ran a reloading business and shipped all of his ammo in plastic bags. And sure enough he had the FBI (or was it the DEA) knocking on his door thinking he was a drug dealer because he bought so many plastic bags. Fortunately the local police were one of his biggest customers and they could vouch for him.

But, back to the original question. No Mary, you are not overreacting, it is only a matter of time before the insurance companies get hold of those databases and you'll find that you won't be able to get insured because of your bad eating (or smoking) habits.

So get yourself a few extra cards with different names and addresses and confuse the hell out of them.
