Hello Wooly Bugger: Yes... the Skeezyks has had a similar life experience. I'm in my mid 60's now. And, looking back, I can't recall a time when I was not a bundle of nerves.

Even now that I've aged into my retirement years, I'm still full of anxiety... mostly over nothing of any particular consequence.
I think after having lived with so much anxiety for so many years, my body no longer knows how to exist any differently. When I think about it, I'm amazed my heart has held up as long as it has. I think if I had been as tough emotionally as I guess I must have been anatomically (not physically), I'd have been a real danger!
