Blunders

I must admit I create lots of blunders. But I learn from them not because I am smart but because I recognize them only after making them. Sometimes I don't recognize them until I review all the pasts moves during the game. Admittedly my time span is not like it use to be. I am trying to reach 1500 to 1600 but somehow when I reach 1400 to 1450 I seem to go backwards. I know I could reach 2000 or more but it will take more dedication on my part. Are there any 82 years young still playing? It seems everyone I play with are young "bloods".
