you know what's wild? i was talking to my friend about this study and we both realized how crazy it is that something as simple as hand washing can make such a huge difference 
. like, it's so easy to just grab some soap and water and go, but the science behind it is actually pretty mind-blowing 
. and then there's this whole thing with the immune response and how our bodies produce interferons to fight off the virus... it's like our bodies are tiny little superheroes 
fighting off these microscopic monsters 
. anyway, i'm kinda obsessed with learning more about colds now 
, who knew there was so much science behind something as boring as a common cold?
