Memory loss or just the flu

Like so many others of our age I occasionally worry about memory lapses.  For instance yesterday I got in my car to go to work, started her up, put her in reverse, hit the gas, and demolished the garage door.  Seems I forgot to open it first.  Now, in my defense, I am battling a severe flu attack and subsequent brain fog, but really. So a very Merry Christmas, for the garage door company at least.
