'A time to die'?
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.
