I was told I've had that problem for many years. It hasn't gotten better or worse. I just live with it and rarely think of the problem. Just a way of life for me.

this is the interesting thing, chip. they're saying it's more of a brain ring than an ear ring [ha! an earring-get it? sheesh, I'm on fire today]. so there might be much to your approach to not thinking about it. might be something of a mind-over-matter situation.
I did find some of the devices interesting, though.
