Genes play a much smaller role than most people have been led to believe. For example, genes can be turned on or off by lifestyle activity. We can see this because many people who have the genes associated with breast cancer never develop breast cancer. And the same has been demonstrated for Alzheimer's etc.
Of course if one lives a poor lifestyle, genes will play a larger role because genes for disease will more likely be turned on.
