Remarks on “Limits to Human Lifespan”

Abstract

We introduce and apply several methods for exploring the human lifespan process in connection to the publication by Dong et al. 2016 on “Evidence for a limit to human lifespan” in Nature in 2016 and the debate emerging mainly published in Nature as well in 2017 along with authors replies. We found it constructive to propose and test several applied methodologies using the centenarian and supercentenarian data sets from various data bases and to give illustrative presentations along with fitting and forecasting. By analyzing these data sets various results are obtained and presented in supporting illustrations and tables. We have provided more tools for analyzing centenarian and supercentenarian data along with the existing methodologies.
