He recently turned 80 and has Parkinson's and heart trouble. But that's not what worries me right now. He had a significant fall last night, and nearly did again tonight. He's sleeping on the couch because he doesn't feel like risking the stairs. I'm not worried about that either. The simplest explanation is usually the correct one, and this was probably just an unfortunate one-time thing. I doubt very much it will be the new normal.

But I would like to see his health improve just enough so he doesn't need a walker, just his cane. My family's over-worrying annoys me much, even if it isn't unfounded. It's not like it's going to make him better.

Heh, if I ever get to be that old, I'm going to make it a point to be as optimistic and sunny as ever. In spite of everything.
