Looking at myself, my genetic background has heart disease, diabetes, cancer and a host of other undesirable genetic stuff that I have no doubt passed somewhat onto my children.
My Grandmother passed away last year, she had Alzheimer's before she passed. I saw her deteriorate over many years. It is a sad thing.
