Larry, that's a diseases known as CRS "Can't Remember S**t", mostly prevalent in older males.
Myself that's why I have two brains, unfortunately one is lost and the other is out looking for it.
It comes and goes, why just yesterday I went out in the garage and got what I went for for on the first try...Amazing!
Two days ago I went to the store and forgot my grocery list, I was able to remember four of the ten items on it. I could have called Barb and got the rest but I forgot I had the phone with me.
See how it comes and goes.
