the dreaded big A because I do experience this phenomenon quite often just lately

Dear Wordcrazy : Fear not!
I ,too, had that thought until I realized I sometimes experienced the same thing when I was a teen!

An MD friend explained to me the difference between normal forgetfullness and The Big A ...
You may forget where you left your keys ... that's normal.
If you are holding a key and do not know what it is ... that's cause for concern.
Whew ... as soon as I found my keys I felt a lot better!
wow
