Some research suggests that mucophagy may be a natural and even healthy activity, which exposes the digestive system to bacteria accumulated in the mucus, thereby helping to strengthen the immune system.
I’ve been saying the same thing for years. Along with that awesome fact are “Men can breastfeed”, “The Gay Bomb”, “Erections After Death”, “Hypnotizing Chickens”, and a few others. You should go and read them all. Be sure to read the comments as well because I was literally LOLing after reading some of them, so don’t miss out on that.
