Modern society has gone overboard with deploying antibacterial soaps, lotions, and cleaning products. They indiscriminately kill germs, yes, but they also wipe out the good bacteria that help maintain a strong and diverse microbiome. “Kills up to 99.9% of common gems,” reads one bottle of hand sanitizer. Everyone has a microbiome, a collection of more than 100 trillion (!) microbes that live on and in our bodies, the majority in our large (and clearly crowded) intestine. The more diverse your individual microbiome, the healthier you are.
