One weird microbe doctors hate: blames antibiotics for your personality

Want to hear something wild? There's a specific microbe called Lactobacillus reuteri that's missing in 95-96% of the population, and its absence could be linked to a host of modern health issues. This microbe, when restored, has been shown in studies to increase oxytocin, the "love hormone," which can improve social behavior and even impact physical attributes like skin thickness and muscle mass. The original discoverer found this microbe everywhere in the 1960s, even in breast milk, but over time, it's virtually disappeared from the human microbiome, likely due to antibiotics and modern living. It makes you wonder how much of our current health crises, from gut issues to social isolation, could be tied to losing these fundamental microbes. It's truly astounding how replacing something our bodies were meant to have can have such widespread beneficial effects, from better sleep to improved body composition and even potentially reversing chronic conditions.
