I don't remember when my memory went bad. har har
All I know is, I've always had to struggle with ways remember things all of my life.
Take for example: when 
I was a waiter at Mgm.
I worked the Exec Station. That meant that I couldn't refer to Clint Eastwood as 'Mr'. I had to say, 'Good evening, Mr Eastwood. May I offer you something to drink?'.
I remember Seigfried sat on my station once singing Framptons "I'm in You, You're in me". I had to think about that one for awhile.
I also had the floor execs.
One was Mr Green who was white, another was Mr White who was black. So, Mr White was black and Mr Green was white. That seemed like a memory grabber.
Then there were the show people:
they would cram 8 in a booth designed for 3.
They'd order their hearts of lettuce salads, their tea with the bag on the side, and so forth.
They never tipped more than 50 cents. I guess in England, food servers don't get tipped. We were lowly scullions.
But that was okay because occassionaly I'd date one of the show girls.
I remember, I offered a showgirl a nickel for her thoughts, and she ripped me off. She had NO thoughts, I mean NONE, but the girl sure could dance.
See now, I forgot what I was talking about.
Oh yes, memory.
These days I have an IPhone. I can just take someone's picture, then email it to myself with their name.
And if someone is talking about something I know nothing about, I google it. If someone is throwing abbreviations around, I can look that up too.
Take for instance, my title these days. I'm a CE in BISD representing ADI for FI. I can't find those in Google, but I can ask and take notes on my IPhone for these things.
I think it's pretty cool. In the current world, you don't need a good brain, all you need is an IPhone.
