Behold, the human immune system's boot camp! That's not dirt—that's a comprehensive microbial education program. While helicopter parents are sanitizing everything in sight, this kid's immune system is getting a PhD in pathogen recognition. Nature's vaccine, if you will. The caption "Child Undergoing Early Antigen Exposure" is just science-speak for "building antibodies while eating antibodies." In 20 years, this kid will laugh at your seasonal allergies from atop their throne of immunological superiority. Darwin would be proud... if he weren't busy rolling in his grave about our modern war on beneficial microbes.
