Genome scans go deep into your DNA

MY MATERNAL grandmother had Alzheimer's disease. Before she died, she forgot our names, our faces and, eventually, how to speak and think. But my grandfather's heartbreak was the most painful to witness. I remember watching the two of them on the sofa together in the months before she died. My grandfather, a sometimes severe man not overly disposed to expressions of tender emotion, cooed into my grandmother's ear: "My bride, oh my bride. I love you. Do you hear me? I love you." She just stared down blankly, folding napkins.
