RESUMEN
Many physical, social, and psychological changes occur during aging that raise the risk of developing chronic diseases, frailty, and dependency. These changes adversely affect the gut microbiota, a phenomenon known as microbe-aging. Those microbiota alterations are, in turn, associated with the development of age-related diseases. The gut microbiota is highly responsive to lifestyle and dietary changes, displaying a flexibility that also provides anactionable tool by which healthy aging can be promoted. This review covers, firstly, the main lifestyle and socioeconomic factors that modify the gut microbiota composition and function during healthy or unhealthy aging and, secondly, the advances being made in defining and promoting healthy aging, including microbiome-informed artificial intelligence tools, personalized dietary patterns, and food probiotic systems.

Barbi et al (Reports, 29 June 2018, p. 1459) reported that human mortality rate reached a "plateau" after the age of 105, suggesting there may be no limit to human longevity. We show, using their data, that potential lifespans cannot increase much beyond the current 122 years unless future biomedical advances alter the intrinsic rate of human aging.

PIP: The value of the Rogers-Castro function in the analysis of migration to the Mexican state of Campeche between 1960 and 1990 is described. Using this mathematical function permits easier analysis of internal migration by age over time rather than restricting it to analysis of five-year age groups. (ANNOTATION)^ieng
