[Aging and dying--reflections on statistical figures].
Aging and death of man have changed decisively during the last centuries. Today, three age-dependent mortalities can be distinguished: the mortalities in the early years of life, those caused by external forces, and the rest of mortality. The logarithm of the rest of mortality is, starting with the 20th year of life, relatively strictly correlated to age. Only this age-dependent mortality can be regarded as a "natural" mortality. It is however enabled only by a culturally and technically extremely favorable environment. The slope of the age-dependent mortality is relatively stable geographically and in the course of time, and is nearly equal for both sexes. Of various diseases, their relative mortalities (expressed in percent of total mortality) indicates an age-specific susceptibility for the causes of death, with high percentages either in youth, in midlife or in high age. The mortality of all cancers was relatively stable during the last decades, whereas the specific mortalities of different cancer sites varied to a much higher degree ("vicarious mortality"). Death is programmed relatively rigidly, as far as it is not related to violence (accidents, poisoning, murder). Perhaps the genetical determination is prevailing. The slope of the programmed part of mortality of woman changes in its steepness after the age of 60, with an increasing rate of mortality.

[Occupation and illness].
1. There are three kinds of work-related diseases: officially recognised occupational diseases; occupational diseases; work-related but unspecific diseases. 2. These unspecific diseases occur more often than would be by mere chance, among certain professional groups. 3. Cancer mortality may increase as a result of occupational cancer-promoting factors, whereas the overall mortality may be unaffected. 4. In such cases, the mortality of other diseases not related to the occupation, is diminished ("vicarious mortality"). 5. The overall cancer mortality is probably not greatly increased by professional influences. This mortality is nearly constant in males and tends to decrease in females. 6. A strong inequality of mortality rates has been found in various occupational groups. The reason for these discrepancies is unknown. 7. Mortality is most strongly related to the mental demands made on individuals by their profession. 8. Death through accidents is six times more frequent in the general population compared with job-related accidents. 9. Health hazard due to occupation is low in relation to mortality, but marked in work-related diseases.
