In 1997, at the reported age of 122, Jeanne Calment passed away in the south of France, setting a benchmark for human survival.
Economist David McCarthy from the University of Georgia and Po-Lin Wang, an expert in risk management and insurance from the University of Southern Florida in the US, are a little more optimistic. They think a true record-breaker might be just around the corner.
As the number of people living to such a ripe old age is statistically somewhat limited, the duo applied a function known as the Gompertz law to better estimate the age any individual might be expected to first reach an assumed mortality plateau. For the most part through history, it seems GMA has remained relatively stable. Improvements in sanitation, health care, and nutrition have predominantly allowed more people to reach old age, compressing the distribution of mortality past a certain point rather than extending it.One was among people born in decades past the mid-19th century, where the GMA jumped by around five years. Though the cause isn't clear, the rise was more pronounced among women.

Population-level impacts of antibiotic usage on the human gut microbiome - Nature CommunicationsHere, the authors study the population-level impact of antimicrobial resistance genes (ARGs). By analyzing 8972 metagenomes and 3,096 gut microbiomes from healthy individuals not taking antibiotics, they demonstrate significant correlations between both the total ARG abundance and diversity and per capita antibiotic usage rates across ten countries spanning three continents. Using a collection of 154,723 human-associated metagenome assembled genomes (MAGs) they link these ARGs to microbial taxa and horizontal gene transfer.
