Forgetting things

I don’t know if it’s old age or me just being stressed, but over the last week or so I’ve noticed that I forget things. I’ve always been able to keep million things in my head. Now I forget everything that’s not written down. Seems like there is no room left in my head. Today a supplier called at work asking if we could have that meeting we talked about two weeks ago. Apparently I had agreed on calling back to set a date. I felt so stupid not remembering. On Friday I totally forgot about a meeting, even though I had looked in my calendar earlier just to check if I had any meetings. So embarrassing! Not only am I getting grey hairs, now I’m forgetting things... Please tell me it’s not only downhill from here…
