The left-handed thing must be genetic, as my wife and son both are. The same applies to double-jointedness (if it's not a word, it is now!); both my wife and I are, and naturally so is our son.
I developed type 1 diabetes at 21; at the time the specialist told me that it was thought to be genetic, even though no-one in my immediate family had it. Interestingly, as I delved more closely into my family history, I discovered that not only did my father die from kidney failure (which I already knew) but also his own mother. Then going back a generation, my great-grandmother (my grandmother's mother) was a diabetic. So you can see how the gene was passed down. Kidney failure is often a sign of border-line diabetes.
I am Australian, from all the lands I come (my ancestors, at least!)
