Yearning for Yesteryear

Is it normal to feel nostalgic about a time one wasn't old enough to even be part of? I am thinking about late 70's Manila...the old model cars, a wide and less crowded Highway 54, empty lots that now have colossal buildings on them. I was too young to remember anything from that time but when I see really old pictures of the old metro, I just can't help but feel that those were the better days and that what we have today are just leftovers...
