However there are some dangers which are so tiny that we don’t even know they’re there. Germs!
Some of these germs are bacteria [say bak-tee-ree-a] which are in the air, water, and the world all around us.
Some of them – ‘good’ bacteria - actually live in our bodies or on our skin and they may keep bad bacteria from growing enough to make us sick. These good bacteria are part of our immune system.
