It’s a good reminder that we live in a world full of microbes who desire to use us as their food source and means of propagation. Without all our defensive mechanism, both those inherent to our physical bodies such as intact skin and a powerful immune system and those as attributes to a conscious mind such as knowledge of hand hygiene and proper sanitation measures, we would not stand a chance against this continual onslaught of invaders. However, for the majority of humans we survive and thrive in the most hostile of microbial environments for decades on end. We are the dominate species on the planet for many reasons but chief among them is that we have been fearfully and wonderfully made.
