A Dave Barry novel is quite the antidote for depressing thoughts.
I just found Big Trouble at Goodwill. My life is so much better than Puggy's, or any of those people, really. The maid, the rich guy, the arms dealer, all had their troubles. Maybe the female policeman had a decent life.
A nap is good. My brain is pretty good at giving me what I want: although last night I was back in the Army again. I'm so glad that is over, I was happy to wake up. They liked me there, but it was too much work.
As far as the diseases of age, I'm fortunate to have a lot of long lived people for ancestors. Diabetes, high blood pressure, and ugliness run in the family, but not cancer or heart disease. I ride a bike a lot, I sort of imagine the end as SPLAT!!!!. Which would be unfortunate, but less stressful than laying around a nursing home listening to the woman in the next bed complain for every second (which happened to my Grandmother that broke her hip). I've got the flu today, something that happens to me more often than most people: every muscle and joint hurts, I'm shivering or alternately sweating, coughing my lungs out. It is so cool now they have a cough medicine that actually works - life does get better sometimes. Two hours out of four I don't cough, what a blessing.
The Carter family wrote a song "Keep on the Sunny side, always on the sunny side, keep on the sunny side of life". Good advice. Maybe a bad cold will do me in finally, as one did my grandfather age 38. Oh well, nothing to worry about, it is just the flu.
