If you are over 40 and leading a fairly busy, active life, it is possible that at least a few times you have had the experience of entering a room of your home and forgetting for what reason you went in there. This is a recurring theme in my life going way back, and since I tend to be easily distracted anyway – because I have a lot on my mind, thank you very much – ageing has only increased the frequency with which it occurs. I forget other stuff, too, though. Actually, forgetting is a way of life for me.
