title: 'A time to die'?
abstract: In both the newborn and the elderly, medical care is increasingly able to prolong or curtail life. It is difficult to assess what effect this may have on the population as a whole and what implication it may have for the interpretation of both short-term and longer-term changes in mortality. The definition of cut-off points for age groups is critical to the interpretation of the way changes in medical care could affect infant mortality rates.
