Yep, when we get too many things going on at once - it is easy to do all those things you describe. We have only so much storage in our short term memory and when the drawers get full, things like this happen. I think with less stress and less things happening, it will get better. However, it is true that as we get older our short term memory gets worse. Some people, like me, never had a very good short term memory, so I am really in trouble now in my 50's.
