The pair has been inseparable ever since they met in preschool, when Dylan learned that Jonah faces a rare battle their other classmates didn’t — glycogen storage disease, or GSD, according to LEX 18. The condition causes Jonah’s blood sugar to drop to potentially fatal levels, forcing his parents to follow an inflexible, round-the-clock schedule of feeding Jonah through a stomach tube in order to keep his metabolism stable, according to ABC News.
GSD does not have a cure. And, to Dylan, that is unacceptable.
So, back in 2013, when he was 6 years old, Dylan wrote a book to help his friend and others struggling with the disease. But, it’s not your typical page-turner, every penny from sales of “Chocolate Bar” — a term used by Dylan to mean “awesome” — goes directly to a lab at the University of Florida College of Medicine in Gainesville, Fla., which is working on a cure for the disease.
