By "new" I mean that only relatively recently in human history (in the last ~100 years) have people been able to live long enough that these become health problems of concern. Before the 20th century, most folks just got sick as a result of an infection of some kind and died. All I am saying is that there will be other new problems that are uncovered as we continue to extend human life-span.
