yeah, lots of folks claim diseases are hereditary, and some might be.
but for the most part, disease is generational because the parents teach the kids how to eat, the way the parents did.
then the kids have their own offspring, and teach them the bad eating habits.
once a 12 year old has tasted the good life of sugary stuff, getting them to eat healthy foods such as sardines and broccoli is next to impossible absent confinement.
Does anyone really thing GHWB was serious about not liking broccoli ? My guess is that he eats it every day.
