Stop in for a cup of coffee

So you are in the Viking Club with myself and Tim. My dad had both hands pinky and ring fingers locked closed
My left ring finger locks closed a lot. Tim had Surgery to straighten both his hands.
Mostly affects people of Scandinavian Ancestry.
Being an Alien I'm just a mutt.
Don't know of others in family ever having a problem with it. Not much functional issues so far. I can feel it pull a little when i straighten my fingers. Has been very slow developing to this point. They don't plan to do anything unless it gets a lot worse. Said if it looked like this on someone in there 20's it would more likely need intervention.
