I had an Indian boss who told me high cholesterol ran in his family, and so he had to go to extreme measures to bring it down. He was on a vegetarian diet with lots of self-imposed restrictions. He was sick a lot, and ended up in the hospital on a regular basis. He told me it was killing off his family. I asked at what age, and he said, "In their 70s." That sounds within the margin of error to me.
