I hear you. Those really were the “good old days”. :)
My daughter knows if and when Alzheimers afflicts me, because I told her: it's when all I talk about is the Summer of '79. I was 25, on a temporary duty assignment in Northern Germany for 3 months. Made a ton of friends there, we were the only Americans for 200 miles. One of the best summers of my life.
My mom was like that when that dreaded disease struck her. She was living back in 1944, when it was actually 2010. Scared the hell out of me when I put the pieces together.
