@BethanyBlack possibly, but I think it has more to do with watching my father (who I look very much like) going from a 6ft 2 18 stone giant to an emaciated skeleton within 8 months, I was 18 & he was 49 when he died. I then watched his dad & brother die in very much the same way within the next 5 years, I have more to fear from my own genes than I could ever fear from the people I see fighting their own battles with illness & disabilities around me.
