And just to add this - I've known people with very high cholesterol, who eat healthy, exercise, and are not overweight. In other words they "take good care" of themselves. Yet there are many health problems associated with high cholesterol, and its also hereditary.
My father, on the other hand, was overweight most of his life, smoked like a fiend, had hypertension, yet HIS cholesterol was about 145, which is well within the healthy range. He died from cancer, perhaps related to some of his other health issues, perhaps not. I too am overweight, medically speaking, obese, yet my cholesterol is in the 150 range, and so far, I have no weight-related health issues, other than cranky creaky knees.
