Caught in the past

My friends say that I dwell too much on the past. They say that I revel in the glory days. Well, today I had breakfast with an older gentleman who got misty-eyed over the mere mention that the restaurant we were eating in used to be a grocery store. This guy is in his mid 60's. I guess my question is, were times really that good? Or do we just seem to remember being faster, stronger, and having more fun than we really had? I guess it would be fun to visit the past, just allow me to pick and choose the dates.
