I don’t think that I have Alzheimer’s — yet, but my memory is not what it used to be. I have never left my keys in the refrigerator, as shown on a TV ad about Alzheimer’s.
Glen Campbell is a famous person, who is making people aware of Alzheimer’s disease. You can read about him in this news story: http://www.nytimes.com/2014/10/26/movies/glen-campbell-on-the-road-with-alzheimers-in-ill-be-me.html
If there are some young whippersnappers out there, who are reading this, and don’t know who Glen Campbell is, you can listen to some of his famous recordings on YouTube.
