Science Frontiers ONLINE No. 41: Sep-Oct 1985 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Death And Social Class A 10-year study of 17,530 London civil servants showed a strong relation between mortality rate and employment grade -- the higher the grade level, the lower the mortality rate. The mortality rate for unskilled laborers was three times that of high-level administrators. Part of the disparity is doubtless due to differences in weight-to-height ratio, cigarette consumption, and amount of leisure-time exercise, which are also strongly correlated with mortality rate. But such personal habits tell only part of the story. Coronary heart disease, which accounted for 43% of all the deaths, was much more ... among the lower employment grades, even among monsmokers. Childhood nutrition and other "early life factors" also play roles. Nevertheless, a factor-of-three is a whopping difference in mortality rate. (Anonymous; "Death, Be Not Proud," Scientific American, 253:68, July 1985.) Comment. There are so many contributing factors here that we cannot be sure if a biological anomaly exists.

Science Frontiers ONLINE No. 86: Mar-Apr 1993 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Must we die? the medfly's answer In the early 1800s, B. Gompertz, an actuary, crafted an empirical law stating that mortality rates increase exponentially with age. Later analyses of census records indicated that the situation was not quite as bad as Gompertz had supposed. Nevertheless, the death rate does increase with age; but we might be able to do something about it. Immortality might be achievable -- if we take recent medfly studies seriously. "Growing old does not increase your immediate risk of dying -- at least, if you are a fruit fly. The chances of a Mediterranean fruit fly ( Ceratitis capitata ... dying on a particular day reaches a peak and then declines, according to James Carey of the University of California at Davis and James Vaupel of Duke University, North Carolina, and Odense University in Denmark. Their results contradict the notion that the death rate rises with age in all species." The upshot is that there may be no genetic limit to an individual medfly's lifetime. And, if these results can be extended to humans, "then medical advances might eventually allow the elderly to live indefinitely." (Bradley, David; "Who Wants to Live Forever?" New Scientist, p. 16, November 14, 1992.) From Science Frontiers #86, MAR-APR 1993 . 1993-2000 William R. Corliss ...
