Brain's going

As I stagger towards the ripe old age of 43 I'm becoming increasingly aware that my memory is fast disappearing. I keep a diary and without it I would not be able to remember what I did yesterday. A case in point recently was comepletely forgetting about a friend's birthday, even though I had been told about it only last week. Not only was I embarrassed but also a bit worried about the state of my grey matter.
