Good days, Bad days

I'm a disabled Vietnam veteran. I've never been wounded, and I didn't have a Purple Heart among the seventeen or eighteen awards and decorations I wore when I retired. My problems are the result of doing everything I could to accomplish the job I had to the best of my abilities, some unusual genetic inheritance, and just plain bad luck. I have three basic problems that make it difficult to do a lot of things: a bad back from chin down, damage to my hearing resulting in tinnitus (ringing in the ears) and hyperaccusis (pain from noise), and near-constant pain and headaches from the other two problems. Like a lot of such problems, some days are better (or worse) than others. Those conditions affect my thinking, and my posting, and my readers need to be aware of that. That's why there are sometimes several days between postings, then several postings all at once.
