Geesh! Paranoia is growing rampant. Thank heavens the federal, state and local governments have access to every bit of my information. That way I don't have to wring my hands and whimper about it. And as to regular folks knowing about me, just ask, I love to talk about myself. Not to mention I have accumulated some really good stories over the last 70+ years.
I suppose some one could try to steal my identity but since any fraud committed by such means wouldn't be done by me, I'd just choose to ignore any blowback. I just inform folks it wasn't me so deal with it. Besides, I am an old fart much closer to the end than the start and that makes ME completely unpredictable.
