In this analogy, the finish line for human beings is the successful reproduction and raising of offspring. The reason that many individuals live far beyond their reproductive years is due to the robust engineering built into the species by natural selection. Modern medical technologies and modified lifestyles have extended the post-reproductive years in industralized societies by protecting the individual from the harsh conditions in which our species evolved.

The use of years of life lost for measuring the level and change of mortality. "The use of the new index of years of life lost allows us to relate mortality by age and causes of death to the change of the life expectancy, at birth or between any given ages. This index replaces the use of the multiple decrement life tables for analyzing the impact of the change in mortality by age and cause of death on the life expectancies....The article presents the theoretical derivation of the index, some examples of its use, and a detailed calculation." Examples provided include Mexico, Chile, and Argentina.

    Extractions: Why We Fall Apart go to main article TERMS TO KNOW FAILURE RATE The risk or frequency of a system's failure; also known as hazard rate. AGING In reliability theory, aging is defined as a phenomenon of increasing risk of failure with the passage of time. GOMPERTZ LAW OF MORTALITY The observation that the logarithm of death rates increases linearly with age. It was first suggested by British actuary Benjamin Gompertz in 1825 for use in the life insurance business. It was found to be applicable not only to humans but also to fruit flies, nematodes, lice, flour beetles, mice, rats, dogs, horses, mountain sheep, baboons, and many other species. WEIBULL POWER LAW The observation that the logarithm of failure rates increases linearly with the logarithm of age. This law was suggested by Swedish engineer and mathematician Waloddi Weibull in 1939 to describe the strength of materials. COMPENSATION LAW OF MORTALITY The observation that the relative differences in mortality between populations tends to decrease with age; also known as mortality convergence in later life. For example, if you manage to reach the age of 90 in a rich, developed country, your odds of survival are only a little better than if you reach 90 in a poor country. LATE-LIFE MORTALITY DECELERATION LAW Death rates level off at extreme old age, and therefore aging apparently fades away. For example, a 100-year-old person is just about as likely to see next year as is a 115-year-old.

    Extractions: [Editor’s Note: In the last issue, Part 1 of this article examined five-year loss trends of transformer breakdowns as reported by international equipment breakdown insurers. In Part 2, the author discusses the aging of the worldwide transformer fleet and shares a global perspective as seen by those in the transformer industry.] By William H. Bartley, P.E. In our previous discussion of a five-year international study of loss trends for transformer failures, we concluded that Insulation Failure was the leading cause. Combined with Design/Material/Workmanship and Unknown causes, these three categories accounted for 65 percent of the total number of transformer breakdowns in our study of losses as reported by members of the International Association of Engineering Insurers (IMIA) ( imia.com ) and 85 percent of the total amount paid out for these claims. Other causes of loss were spread among: Oil Contamination; Overloading; Fire/Explosion; Line/Surge; Improper Maintenance/Operation; Flood; Loose Connection; Lightning and Moisture (see An International Analysis of Transformer Failures, Part 1, The Locomotive, Winter 2004, Vol. 78, No. 1). Transformer Aging We did not categorize "age" as a cause of failure. Aging of the insulation system reduces both the mechanical and dielectric-withstand strength of the transformer. As the transformer ages, it is subjected to faults that result in high radial and compressive forces. As the load increases, with system growth, the operating stresses increase. In an aging transformer failure, typically the conductor insulation is weakened to the point where it can no longer sustain mechanical stresses of a fault. Turn-to-turn insulation then suffers a dielectric failure, or a fault causes a loosening of winding clamping pressure, which reduces the transformer's ability to withstand future short circuit forces.

    Extractions: ¿Cómo Identificar a los Pacientes con Riesgo de Osteoporosis? Dr. Joseph Melton, Profesor de Epidemiología, Mayo Medical School. En esta presentación se tratará la manera de identificar a los pacientes con riesgo de fracturas osteoporóticas. Además del tratamiento de los pacientes que tienen baja densidad ósea, las posibilidades de intervencion son más amplias. La incidencia de las fracturas en hueso osteoporótico, especialmente la fractura de cadera, aumenta con la edad: es decir. son “gompertzianas”. Hace 400 años, Benjamin Gompertz, actuario inglés, descubrió que la incidencia de muerte aumentaba en forma exponencial a medida que aumentaba la edad y aprovechó esta información para establecer las primas de los seguros de vida en Inglaterra. Recientemente se ha descubierto que la tasa de incidencia de muchas enfermedades también aumenta exponencialmente con la edad. En un gráfico de edad versus incidencia de fracturas de cadera se ve cómo la curva aumenta en escala logarítmica y lo mismo ocurre con otras enfermedades como, por ejemplo, la diabetes mellitus tipo 2, los accidentes vasculares encefálicos y el cáncer de mama. Sucede que la mayoría de las enfermedades crónicas que más nos afectan, como sociedades occidentales, aumentan exponencialmente con la edad; son todas gompertzianas. Los adenocarcinomas, la aterosclerosis, artrosis, enfermedad de Alzheimer, cardiopatía coronaria, accidentes vasculares encefálicos y, también, la osteoporosis; a diferencia de otras enfermedades que no aumentan exponencialmente con la edad y que no son gompertzianas, como la enfermedad de Hodgkin, la artritis reumatoidea, el lupus eritematoso sistémico, la esclerosis múltiple, el asma, la hepatitis y la enfermedad intestinal inflamatoria.
