I have learned a lot about how good healthy bacteria spread from mother to son, or mentor to student, or friend to friend has a deep impact on how the two people grow. Most bacteria are constantly growing in intelligence and learning from its surroundings.
If anyone has more information on studies about bacteria or germs I would love to hear them.
Meanwhile, I plan to wash my hands with only water, and never use shampoo or take any medicine. I plan to host great bacteria inside my body!
