Cancer. Disease that has probably touched your life in some way. More than 40 percent of americans will be diagnosed with cancer during their lifetime, and more than 20 percent will die from it. When we talk of cancer, we often refer to it as if it were a single disease. But in reality, it is many diseases. One of the women i was counseling today had a Family Member who had uterine cancer, one had Breast Cancer, one had colon, one had cervix. I had to try to explain to her that these diseases were cancer, but were not all related. The cause of each was very different. Cancer is a general name for more than 100 different diseases. But what all cancers have in common is uncontrollable growth of cells. Cells are the Building Blocks of all organisms they all grow and divide, but as a rule, only when the body needs new cells to stay healthy. But once cells become cancerous, they reproduce indefinitely. Cancer develops in cells that have damaged genes, or mutations. Harold varmus human cance

Oh, goody. One, two, three, four, five, six. Aging is the pattern of life changes that occur naturally as people grow older. Contrary to popular belief, aging does not begin the moment you find your first gray hair, nor does it begin at 65. Some changes begin at birth and continue until death, others begin at maturity, and end at death. The physiological changes that come with aging are a natural phenomenon and unavoidable. Unfortunately. Human bodies are a bit like american cars, they have planned obsolescence. Our genetic blueprint makes sure that we grow old enough to have children, but once thats been done, theres relatively little selection. And so as we grow older, our parts begin to wear out. In essence, we begin to rust. Narrator during youth, when lung capacity is the greatest, muscles the firmest, motor skills quickest, endurance at its peak, the body enjoys its finest years. But after the age of about 30, the body begins an inexorable decline. Although it will still be decad
