One of the solutions of healthcare may lie in the analysis of the longevity of scholars by probing the underlying reasons and determining factors. This study sets out to investigate the reasons why scholars in mathematics, physics, and chemistry generally live a longer and healthier life, and in particular, why longer than the common value, by compiling and analyzing data from information on those scholars. The society at large can learn from the research results of this paper which indicate that reading can, to a certain extent, lead to a long and a relatively healthy life.

Given the practical implications of looking into the health of scholars, it is of great priority to figure out the factors that are generally agreed to be the contributors to sustained health, to which end, this paper sets out to collect the mainstream insight into all possible influencing factors. Three research scheme are proposed in this paper under which basic personal information are collected first from 520 scholars in mathematics, physics, and chemistry for an analysis of their longevity performance via a comparison with common values under the demographic perspective to derive the raw longevity information of the scholars. Also, the ways they manage to maintain health are ascertained, on the basis of which the reasons for their sustained health are provided.
