Grandpa (age 95) and I on our trip to Northern Sweden in 2011 had the opportunity to taste surströmming, which is fermented Baltic sea herring. It's known as the stinkiest food in the world and you aren't allowed to eat it inside! It was a cross between rotting fish and outhouse in smell.
Apparently it promotes a long life because Grandpa is still going at 98 .... and he has a girlfriend!
