Aside from old age, I think by far the two biggest killers in my family are cancer and strokes, although not of the same type... I'm collecting enough different types of cancer it's like playing body part bingo. I have however noticed some themes, in that one side of my family had a direct line suffering bronchitis and/or emphysema and my cousin and her son have been diagnosed with COPD, so we suspect that's what they all had. The same line also seems to have a predisposition to depressive disorders, which myself and my mother suffering, her mother having some hints, her grandmother attempting suicide and her great grandmother dying after refusing to have an operation; unfortunately not a lot of information available to analyse that, given that it was, and mainly still is, a taboo subject. There's some suggestion that autistic spectrum disorders may also have a genetic link, but I don't know where that might have come from.
