would you expect the person to have been in an incubator for the years between the ages of 3 and 13? I doubt it. I bet you those kids recall and cherish very much about the music and general culture during those years.
I was 1 year old when 1980 happened. I strutted around with my Thriller jacket and parachute pants. I had most of the transformers, star wars, and GI Joe action figures! I watched Transformers/He-Man/GI Joe religiously. Try to take that away from me, punk!
I'm very clearly an 80s kid because I came of a certain age during that decade, and a 90s kid because I experienced the next tier of social/biological development during that decade.
