forget about it

I was speaking with a friend today, and we were trying to remember some people from not too long ago. I said, "lately I forget things that just happened or names of things from not too long ago, but I don't forget things from a long time ago." He says something about, we forget  nouns first, and we say things like ," I had to replace the  ,  ummmm , the  ummmm  "water pusher" , what he meant to say was  "pump".  Anyway, then I realized I forget things that happened a while ago too, and some other things, Basically,
"I forgot  what I forgot"
                          To quote a secretary I once had " I think you have Ol'timers disease"
