Here's the 101, as best as I recall: Most demi-gods are dyslexic and ADHD. Dyslexic because their brains are programmed to work in Ancient Greek, and AHDH because they're born warriors and must have all senses honed and paying attention to many things happening in all directions, all at the same time. If they focus on just one thing, well, the *other* monster will get them!
