We know that cancer and the aging process are linked, as cancer is probably the end result of malfunctions in the normal telomere cell senescence mechanism. The older you get, the more likely you are to develop cancers - the body is a complex machine, and all machines wear out in time. ScienceDaily reports on a study confirming that most of our ancestors didn't live long enough (or smoke enough) to develop cancer. As Aubrey de Grey has pointed out, tackling cancer is both difficult and absolutely necessary to any serious effort to greatly extend the healthy human life span. Fortunately, a greal deal of funding, effort and public support is dedicated to beating cancer. Real progress is being made.
