Short-Term Memory: "Fagetta 'bout it'"

All this worry about losing short-term memory as you grow older is much ado about nothing...because:

(1) 2/3rds of my life I don't want to remember anyway.

(2) If my memories are bad, my wife will remember them for me. If my memories are good, my friends will pooh-pooh them and say the never happened.

So...what's the point of even discussing...whatever it was we were talking about.
