I'm Icelandic, and my last memory of eating shark was when I was a kid and was visiting my friend. I puked and never tasted it again.

I don't mind keeping traditions around. These foods, however, only existed because we didn't have any better way to preserve them. We do now, and I neither see any reason nor feel any urge to eat rotten food. This sentiment is shared by most icelandic people I know. Very few people(that I know) consider these things to be a delicacy. It's mostly the older generations.
