who do you think was sick the most as a kid?
Probably Scout, if for no other reason than having so many older brothers who were all bringing home germs from school and from running around the city. He was probably exposed to every contagious disease on the planet growing up, but lucky for him that means he’s built up immunity to a lot of things as an adult and doesn’t get sick much anymore.
Sniper would be second, just because he seems like the type of kid who would’ve gotten sick a lot. But since he lived in the middle of nowhere, that would also limit his exposure to contagious illnesses. I imagine he did get a few nasty infections from not cleaning injuries like skinned knees properly, also, though.
I think Medic would have gotten sick the least due to his family’s knowledge of proper health practices and access to medicines. However, whenever he did get sick he was a big baby about it, because it happened so rarely. He would just lie in bed all day whining and asking for chicken soup.
