There are various versions of what Twain said or didn't say in  this regard.  Whichever version you choose, I can subscribe.

Loss of mobility is grievously annoying.  I have lost most of the use of my left side.  This is usually result of a stroke, but in my case, is a peculiar infection.  I have weakness and lack of balance on that side.  I can't walk unaided.

Also grievously annoying is that I can barely type.  My left hand is my "typing hand," due to an injury to my right hand years ago.  I have lost "fine motor control" in  my left hand, which means my typing is erratic and slow -- not an  ideal combination.  That probably precludes my writing of my autobiography, even though it wouldn't be very long anyhow.

I am well cared for by daughter and granddaughter, plus Ladyfriend on weekends.

All is well, except my attitude, which is really crappy.  I start physical therapy on Monday, which I am really looking forward to. 

"This, too, shall pass."  Just not fast enough.

Y'all keep up the good work, and

Take care,

Russ
