The question is whether smaller humans live longer, and we should have plenty of data on that. Here's a study published in the Western Journal of Medicine that cites "FINDINGS SUGGESTING THAT SHORT STATURE IS HEALTHIER": https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1071721/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1071721/ e.g. "The researchers, Willcox etal, did not attribute this superior health to genetics because when younger Okinawans migrate to mainland Japan, Hawaii, or the United States, they soon acquire the chronic diseases of the host population.
