I can't see the link here. I have had DD for nearly 40 year. Appendix removed 12 years ago but brother sister and father all have DD and no appendix issues.

The statistical links as I understand them are DD, LD, Frozen Shoulder, Diabetes. I have have had LD since my early teens and DD since my early 20's. 5 years ago I had a bought of frozen shoulder (Both shoulders at the same time which I understand is very rare). I have all the markers for type 2 diabetes but don't have it yet. Only a matter of time I suspect.

Other than curled up hands I am in perfect health. Still play tennis 3 times a week and 2-3 gym sessions per week.

My view of the world is that DD is the best genetic defect on offer. Sure beats all the other nasties out there.

I still have my appendix, but what that has to do with my hands I don't know! Although I don't have my tonsils or wisdom teeth!!! As far as I can see mine isn't hereditary either. Neither of my parents have it, Mum is in her 60's and Dad is in his 70's. But after years of typing/writing at work, I've come to the conclusion that I've worn my hands out! I always thought I'd get arthritis but got this weird, pain of disease instead!!
But Seph and Wach are right...there are worse things out there!

Take care all!

Thanks Wolfgang you're right!
Although my Dad is Italian, is it a common disease there?
Also my Mum is part German and they visited Germany a month or so ago and none of her relatives had
heard of it! I got her to ask them as they are the only relatives we have left on her side to ask!
I shall see what happens in the future!

Best Wishes
Anna
