Being sick is not normal, so why are black people accepting being sick as a normal lifestyle?

*It runs in the family

*It's hereditary

*"My mom died from heart disease, so it's expected

*"Girl didn't you know, I have diabetes!!!"

These are things I hear black people say all the time, and are accepting  being sick as something that is meant to happen, but can it be avoided? What can be done to break the cycle?
